摘要:
N-Phenyl-C,C-diphenylketenimine adds to Z-1-butyl-1-dibutylboryl-2-diphenylphosphino-2-phenylethene to give 2,2,3-tributyl-6-diphenylmethylideno-1,4,5,5-tetraphenyl-1-aza-5-phosphonia-2-boratacyclohex-3-ene, which rearranges into 4,6-dibutyl-2-diphenylphosphino-1,1,3,5-tetraphenyl-3-aza-4-boradeca-1,5-diene upon heating. Its crystal structure has been established by X-ray analysis.
