Trimethylsilyldiazomethane is used as one-carbon homologation reagent; stable, safe substitute for diazomethane;participating in the synthesis reactions of insertion reactions;ketenylation reactions;preparation of homoallylic sulfides;pericyclic reactions;[C-N-N] 1,3-dipole for the preparation of azoles. | [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. |
