Unexpected Staudinger reaction of α-azidoacetonitriles α-phenyl substituted with triphenylphospine. Preparation, X-ray crystal and molecular structures of a phosphazine, an aminophosphonium carbanion salt and a phosphazide, with (Z)-configuration

Staudinger reaction of α-azidophenylacetonitrile with triphenylphosphine in 1:2 molar ratio provides the triphenylphosphazine 4 derived from α-diazophenylacetonitrile, whereas 2:1 molar ratio the final product is found to be the aminotriphenylphosphonium salt of phenylmalononitrile 6. However, the Staudinger reaction of α- azidodiphenylacetonitrile with triphenylphosphine affords the corresponding (Z)-phosphazide 17. The crystal and molecular structures of compounds 4,6, and 17 have been determined by X-ray analysis. Compound 17 is the first isolated phosphazide which presents the (Z)-configuration with respect to the central N,N bond of the PN3C moiety (P-N-N-N= 0.0(3)°).

Tautomerism of 5,5-Diphenyldihydro-4H-1,2,3-triazol-4-one and 5-Amino-4,4-diphenyl-4H-1,2,3-triazoles

Methylation of the 5-amino-4H-1,2,3-triazole 5 affords the N-methyl- (12) and the N,N-dimethylaminotriazole 13.X-ray diffraction analyses show that the tautomer 5b exists in the crystal and that 5b and 13 possess similar structures and atomic distances.Bo
