General considerations

All manipulations were carried out using standard Schlenk and glove box techniques under an

atmosphere of high purity dinitrogen Pentane was distilled over NaK alloy (2575) while THF

hexane and toluene were distilled over molten potassium 1H 13C1H 29Si1H and 11B1H NMR

spectra were recorded on either Bruker DPX300 or Bruker AvanceIII 400 spectrometers and were

referenced to the resonances of the solvent used external SiMe4 or external BF3OEt2 Mass spectra

were recorded on an Agilent Technologies 5975D inert MSD with a solid state probe IR spectra

were recorded as Nujol mulls using a Agilent Cary 630 spectrometer operating in attenuated total

reflectance (ATR) or transmission modes Melting points were determined in sealed glass

capillaries under dinitrogen and are uncorrected Microanalyses were carried out at the Science

Centre London Metropolitan University The compounds [(ArNacnac)Mg2] (Ar = Xyl1 Mes2 or

Dep3) [(MesNacnac)Mg2(-DPE)]4 [LZnBr]5 [TBoLZnBr]6 K[PhBoL]7 [(LdaggerMgI)2]8 and

Synthesis of [(XylNacnac)Mg2(-DPE)] (5) To a stirred solution of [(XylNacnac)Mg2] (040 g

0605 mmol) in toluene (60 mL) at -40 degC was added neat 11-diphenylethylene (022 mL 121

mmol) via a microsyringe The yellow solution became deep red upon addition and was then

warmed to room temperature Volatiles were removed in vacuo and the residue taken up in hexane

(ca 20 mL) and stored at -30 degC overnight yielding deep red blocks of 5 Isolation of the crystals

and further evaporation of the filtrate gave a second crop of crystals (040 g 78) NB 5 may be

cleanly prepared in situ for further reactions by the addition of one equivalent of 11-

diphenylethylene to a stirred solution of [(XylNacnac)Mg2] in toluene at room temperature Mp

Vant Hoff analysis of variable temperature 1H NMR spectra of [(XylNacnac)Mg(μ-

CH2CPh2)Mg(XylNacnac)]

In an NMR tube equipped with a JYoung stopper a solution of [(XylNacnac)Mg(μ-

CH2CPh2)Mg(XylNacnac)] C (4000 mg 00606 mmol) in toluene-d8 (600 uL 01010M) was

subject to a variable temperature 1H NMR spectroscopic analysis The integrals for the signals of

free diphenylethylene CPh2CH2 A protons and NCCH protons of the ligands of both C and

[(XylNacnac)Mg2] B were used for the determination of the equilibrium constant of the reaction

between B and A to give C Temperatures between 20 ordmC (293 K) to 60 ordmC (343 K) at 10 K

increments were used for the vant Hoff analysis

2 X-Ray Crystallography

Crystals of 5-13 [LdaggerMgMgLdagger] and [(PhBoLCdI)2] suitable for X-ray structural determination were

mounted in silicone oil Crystallographic measurements were made using either an Oxford Gemini

Ultra or a Bruker X8 diffractometer using a graphite monochromator with Mo K radiation ( =

071073 Aring) or Cu K radiation (154180 Aring) or the MX1 beamline of the Australian Synchrotron (

= 071090 Aring) The software package Blu-Ice10 was used for synchrotron data acquisition while the

program XDS11 was employed for synchrotron data reduction All structures were solved by direct

methods and refined on F2 by full matrix least squares (SHELX-1612) using all unique data

Hydrogen atoms are typically included in calculated positions (riding model) Crystal data details

of data collections and refinements for all structures can be found in their CIF files and are

summarized in Table S6

General considerations

All manipulations were carried out using standard Schlenk and glove box techniques under an

atmosphere of high purity dinitrogen Pentane was distilled over NaK alloy (2575) while THF

hexane and toluene were distilled over molten potassium 1H 13C1H 29Si1H and 11B1H NMR

spectra were recorded on either Bruker DPX300 or Bruker AvanceIII 400 spectrometers and were

referenced to the resonances of the solvent used external SiMe4 or external BF3OEt2 Mass spectra

were recorded on an Agilent Technologies 5975D inert MSD with a solid state probe IR spectra

were recorded as Nujol mulls using a Agilent Cary 630 spectrometer operating in attenuated total

reflectance (ATR) or transmission modes Melting points were determined in sealed glass

capillaries under dinitrogen and are uncorrected Microanalyses were carried out at the Science

Centre London Metropolitan University The compounds [(ArNacnac)Mg2] (Ar = Xyl1 Mes2 or

Dep3) [(MesNacnac)Mg2(-DPE)]4 [LZnBr]5 [TBoLZnBr]6 K[PhBoL]7 [(LdaggerMgI)2]8 and

[LGeCl]9 were prepared by literature procedures All other reagents were used as received

Synthesis of [(XylNacnac)Mg2(-DPE)] (5) To a stirred solution of [(XylNacnac)Mg2] (040 g

0605 mmol) in toluene (60 mL) at -40 degC was added neat 11-diphenylethylene (022 mL 121

mmol) via a microsyringe The yellow solution became deep red upon addition and was then

warmed to room temperature Volatiles were removed in vacuo and the residue taken up in hexane

(ca 20 mL) and stored at -30 degC overnight yielding deep red blocks of 5 Isolation of the crystals

and further evaporation of the filtrate gave a second crop of crystals (040 g 78) NB 5 may be

cleanly prepared in situ for further reactions by the addition of one equivalent of 11-

diphenylethylene to a stirred solution of [(XylNacnac)Mg2] in toluene at room temperature Mp
