Wittig reagents (1a,c) react with phthalimidobenzoic acid azide (2a) to give the new products 3a, 3b, 3c, and 5, respectively. On the other hand, methylenetriphenylphosphorane (1b) reacts with azides (2a,b) to afford the corresponding 1,5-disubstituted-1,2,3-triazoles (4,6). Structural reasoning for the new products was based on compatible analytical and spectral data.
