Tetrachloro-l,3-disilacyclopentane

Platinum-catalyzed double silylations of alkynes with bis(dichlorosilyl)methane 142 have also been studied by the same research group <2006JOM604>. Indeed, bis(dichlorosilyl)methane undergoes the two types of reaction - double hydrosilylation and a dehydrogenative double silylation with an alkyne, in the presence of Speier s catalyst, to give l,l,3,3-tetrachloro-l,3-disilacyclopentane and l,l,3,3-tetrachloro-l,3-disila-cyclopent-4-ene (Equation 24). 

All investigations into l,l,3 3-tetrachloro-l,3-disilacyclopentane 351 are related to the work done on (Cl2Si-CHj)3. The is accessible by reaction of CljSi-CH - CHj SiClj CHjCl with Mg [147], Photochlorination of 351 proceeds through a number of stages ...
