Abstract
The metallo silanes C(5)R(5)(OC)(2)(Me(3)P)M-SiPh(2)H (4a-c), are conv erted into the corresponding metallo silanols C(5)R(5)(OC)(2)-(Me(3)P) M-Si(2)Ph(2)OH [R = H, M= Cr (6a); R = Me, M = Mo (6b); M = W (6c)] by oxofunctionalization with dimethyldioxirane (5). Treatment of 6b, c w ith the chlorosilanes Me(2)Si(R)Cl [R = H (3b), [R = Cl (3c)] in the p resence of triethylamine gives access to the metallo disiloxanes C(5)M e(5)(OC)(2)(Me(3)P)M-SiPh(2)OSiMe(2)R [M = Mo, R = H (7a); M = W, R = Cl (7b)]. The structure of tungsten silanol 6c is determined by X-ray diffraction analysis.
