โฆ Synopsis
FROU the reaction of dichlorodiphenylsilane with sodium, Kipping and COworkers 1 obtained by careful fractionation of the very complex mixture of products a substance called Compound (B). They designated this compound as octaphenylcyclotetrasilsne. It was recently reported' that their Compound (A) was octapheqylcyclotetrasilane and not a compound containing "two tenralent silicon atoms". There was a high degree of reasonableness at that time for such a structure in view of some uncommon reactions. V!e

Labelling studies of the conversion of (5, RI= Rz= Me) to ( 9) on reaction with methyl lithium are consistent with an intermediate (4, RI= Rz= Me) or a carbenoid with no plane of symmetry through the ring, in which selective migration of Ha (Hb and Hd in (I, RI= Rz= Me)) occurs.
