M. Oestreich et al. studied the copper-catalyzed aldimine addition of nucleophilic silicon, released from Me2PhSiBpin reagent in protic medium (151). The application of tert-butyl(ben-zylidene) carbamate as aldimine component gave rise to tert-butyl- [dimethyl (phenyl) silyl] (phenyl) methyl carbamate 226 in moderate yield. The replacement of CuCN catalyst by NHC— copper(I) complex (L CuCl) led to higher yield of this compound (Scheme 24.28) (152). 

Successful results have been obtained (Renfrew and Chaney, 1946) with ethyl formate methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, sec.-butyl and iso-amyl acetat ethyleneglycol diacetate ethyl monochloro- and trichloro-acetates methyl, n-propyl, n-octyl and n-dodecyl propionates ethyl butyrate n-butyl and n-amyl valerates ethyl laurate ethyl lactate ethyl acetoacetate diethyl carbonate dimethyl and diethyl oxalates diethyl malonate diethyl adipate di-n-butyl tartrate ethyl phenylacetate methyl and ethyl benzoates methyl and ethyl salicylates diethyl and di-n-butyl phthalates. The method fails for vinyl acetate, ieri.-butyl acetate, n-octadecyl propionate, ethyl and >i-butyl stearate, phenyl, benzyl- and guaicol-acetate, methyl and ethyl cinnamate, diethyl sulphate and ethyl p-aminobenzoate.

Dimethyl[l-phenyl-4-[(tert-butyldimethylsilyl)oxy]butyl]phosphonate. (see Sch. 26 below) A solution of l-phenyl-4[(ter/-butyldimethylsilyl)-oxy]butyl dimethyl phosphite (5.94 g, 16.0 mmol) in benzene (160 mL) was divided between six quartz test tubes. The solution was degassed by bubbling argon through it for 15 min. The solution was then irradiated by a 450 W Hanovia medium pressure UY lamp. The conversion of the starting material was complete in 8h. Benzene was removed, and the yellowish liquid residue was dissolved in chloroform and applied to a silica gel column. This was eluted first with chloroform and then with 1% MeOH in CHC13. The title phosphonate was obtained as a colorless liquid (4.2 g, 72%) [133].
