A general picture is given of the reactivity of the two Fischer-type alkyl(hydrazino)carbene complexes (CO)5Cr=C(CH3)N(Bn)N(CH3)2 (1) and (CO)4Cr=C(CH3)N(Bn)N(CH3)2 (3

The preparation of ylides of the general structure RC(=NR')N-N+(CH3)2CH2Ar (14) is described.Thermolysis of 14a (R = CH3, R' = H, Ar = C6H5) gave dimethylamine and 2,4-dimethyl-6-phenyl-s-triazine.Thermolysis of ylides 14b (R = C6H5; R' = CH3, Ar = C6H5) and 14c (R = C6H5, R' = CH3, Ar = p-tolyl) gave dimethylamine, ArCH=NCH3 and 1-methyl-2-Ar-4,6-diphenyl-1,2-dihydro-s-triazines (19a,b).Triazines 19a and 19b were also prepared by condensation of N-methylbenzamidine with benzaldehyde and p-tolualdehyde, respectively.Thermolysis of 14d (R = C6H5, R' = CH2C6H5, Ar = C6H5) gave 1-benzyl-2,4,6-triphenyl-1,2-dihydro-s-triazine (19c) and N-benzylidenebenzylamine.Mechanistic aspects of these reactions are discussed.
