mp 62–65°C; bp 87–90°C/40 mmHg. | [Uses]
O-(tert-Butyldimethylsilyl)hydroxylamine (tert-butyldimethylsilyl-O-hydroxylamine)is used to induce the cleavage, during solid supported synthesis of hydroxamic acids. It also finds it uses as a chemical additive and an intermediate. | [Preparation]
the reagents are most conveniently prepared
by treatment of hydroxylamine hydrochloride with
ethylenediamine in dichloromethane, followed by the appropriate
chlorosilane.A two-step procedure using ammonia in
place of ethylenediamine has also been reported. |
