The most air-stable disilene, tetrakis(2,4,6-triisopropylphenyl) disilene was obtained by the direct treatment of dichloromonosilane, bis(2,4,6-triisopropylphenyl)dichlorosilane, with lithium naphthalenide. The Si=Si bond, the distance being 2.144 Å via X-ray structure analysis, was found to be sterically covered with the four bulky substituents.

SzcPnmayy Chlorotris(tripheny1phosphine)rhodium has been found to be an extremely effective catalyst for the hydrosilylation of carbonyl compounds. RHODIUM(I)complexes are effective catalysts for various reactions1 However, catalysis of the hydrosilylation of carbonyl compounds has not hitherto been reported.
