Abstract:
The new phosphoranylideneketene, (cyclohexyl)₃PCCO, was synthesized and structurally as well as spectroscopically characterized. Ph₃PCCO and (cyclohexyl)₃PCCO were found to be weak ambidentate Lewis bases capable of donating to strong Lewis acids via the ylidic carbon or the carbonyl oxygen.
