Silanones thermal generation

More recently, Belzner et al. reported a new type of oxygen transfer reaction from isocyanates to bis[2-(dimethylaminomethyl)phenyl]silylene (8)18 which was thermally generated from the corresponding cyclotrisilane 7, and they obtained some convincing results of the involvement of silanone 9 (Scheme 3). However, they found that silanone 9 is not stable enough to be isolated. Only cyclic di- and trisiloxanes 10 and 11 (i.e., the cyclic dimer and trimer of the silanone 9) were obtained together with the corresponding isonitrile as other main products when... [Pg.127]

Three additional processes are believed to involve the thermal generation of silanones in solution (i) cycloreversion, (ii) silanolate fragmentation and (iii) oxygen atom abstraction by a silylene. [Pg.1123]

Thus, silanones are generated from (141) by thermal or photochemical means. 145 as js hexamethyl-1.4-disiiabenzene from (142). 146 The adducts... [Pg.503]
