Uses
(Trimethylsilyl)diazomethane is used as an analyte in the determination of some phenolic organohalogens in human serum by GC-MS.
Preparation
Trimethylsilyldiazomethane is prepared by the diazo-transfer reaction of trimethylsilylmethylmagnesium chloride with diphenyl phosphorazidate (DPPA) (eq 1).
General Description
(Trimethylsilyl)diazomethane is considered as a non-explosive substitute to diazomethane for the homologation of carbonyl derivatives, mainly ketones, via reactions such as Tiffeneau-Demjanov rearrangement.
