Article abstract of DOI:10.1016/S0040-4039(00)97785-2

Acidic methylene compounds are conveniently converted to diazo compounds in high yields by azidotris(diethylamino)phosphonium bromide, 1, in diethyl ether using only a catalytic amount of base. The product diazo compounds are easily separated from the co-product hexaethylphosphorimidic triamide hydrobromide.
