Untersuchungen an diazoverbindungen und aziden: LXIII. Silylierung von α-diazophosphon- und -carbon-säureestern mit silyltriflaten☆

Abstract α-Diazo-phosphonates and -carboxylates react with silyl triflates to give the silylated α-diazoesters. In the case of t-butyl-α-diazoacetate the C -silylation is accompanied by a transesterification. Solvolysis of the C -silylated diazoacetic acid silylester by t-butylamine as well as by methanol takes place.
