摘要
the basis of his own and literature data, the author considers and theoretically substantiates the third route to the formation and decomposition of linear and cyclic oligo- nand polysiloxanes, involving intramolecular reactions of geminal fragmentation of >Si(OR)X group with the intermediate formation (alpha-elimination) of short lived silanones R-2'Si=0. The latter further undergo polymerization or insert into the Si-X bonds (X = 0, Cl, etc.) of trapping reagents. (C) 1998 Elsevier Science S.A. All rights reserved.
