  The UV photolysis of teh permethylated linear polysilanes Me(Me2Si)nMe (I), with n = 4 to 8, in cyclohexane at, or al little above, room temperature has been found to proceed simultaneously by two different routes, one of these involves contraction of the chain with loss of dimethylsilylene species to produce octamethyltrisilane which was usually very resistant to the photolysis), while the other comprises

  Five new permethylated linear polysilanes of the formula CH3[Si(CH3)2]nCH3, where n is equal to 8, 9, 10, 11 and 12, have been prepared from the co-condensation of appropriate chlorosilanes using sodium-potassium alloy as condensing agent in a benzene-ligroin or benzene-n-heptane mixture. These compounds are all white crystalline substances. The melting points display a regular progression as the number

• Palladium-catalyzed insertion of isocyanides into the silicon-silicon linkages of oligosilanes

  Full details of a study on the reactions of oligosilanes with isocyanides promoted by a palladium catalyst are described. Heating a mixture of oligosilanes and excess 2,6-disubstituted aryl isocyanide in the presence of palladium(II) acetate led to the complete insertion of isocyanide into all silicon-silicon linkages, giving oligo(silylimine) derivatives. The oligo(silylimine)s have been isolated and characterized so far in the complete insertion reaction with oligosilanes up to a hexasilane. Use of the limiting amount of isocyanide permitted insertion of isocyanide into predominantly the terminal silicon-silicon linkages. The mode of the insertion reaction depends on the substituent at the silicon, e.g., tetrasilanes with phenyl groups on the internal silicon atoms favorably underwent the insertion reaction at the terminal silicon-silicon linkages, resulting in the partial insertion. The bulkiness of the ortho substituents on the aromatic isocyanide was also found to have much influence on the insertion; hence, 2,6-diisopropylphenyl isocyanide favored the partial insertion. New skeletal rearrangement of oligosilanes took place in a palladium-catalyzed reaction of substituted aryl isocyanide with tetra- and hexasilanes, forming 3,3-bis(silyl)-l-aza-2, 4-disilacyclobutane derivatives. The rearrangement, which is unique and intriguing in that the product is properly reconstituted from four fragments of the tetrasilane and two fragments of the isocyanide, was promoted in the copresence of a tert-alkyl isocyanide.
