摘要
The carbene-like compounds 1, which are formed almost quantitatively from phosphanyldiazomethanes already at T less-than-or-equal-to 35-degrees-C if the tetramethylpiperidine (tmp)-R residue is one of the substituents on the phosphorus, are stable for several weeks in solution. With the exception of 1 a, the compounds 1 react with tBuNC to give the ketenimines 2. a, R = NiPr2, R' = Me; b, R = NMe2, R' = Me; c, R = NMe2,R' = iPr; d, R = Ph, R' = Me.
