Hence the principal initial ethosyacetylene adduct under Chldhamer's conditions is CHz=C( OEt)SCiH7 and not c.i.7- CiH;SCH=CHOEt. This initial adduct shows essentially cine peak on a gas chromatogram (one o f the t w o minor peaks comes from CH:,COSC;H;;, but on standing this peak be- comes minor aiid several others appear, the major cine of which derives from C;H;SCH=CHOEt, and ancithcr from CiHiSH. Presumably tlie initial l,l-,idduct reverts to starting materials, which recombine in a free radical proc-
