Silanones from silylenes

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]

The silylene 79 abstracts oxygen or sulfur from isocyanates and isothiocyanates413. Cyclic siloxanes are the products with isocyanates (equation 129) these probably arise by polymerization of the silanone, Ar2Si=0 (83). [Pg.2552]
