Abstract

Benzophenone semicarbazone (I) reacted with carbon monoxide at about 4000 psi and at 235-245° in the presence of preformed dicobalt octacarbonyl as catalyst to yield 3-phenyl- phthalimidine (II), 3-phenyl-2-(N benzhydrylcarboxamido) phthalimidine (V), N, N'- dibenzhydrylurea (VI), and N-benzhydrylurea (VII). At 200-220° substance I gave compound VII, benzophenone azine (VIII), and benzophenone 4-benzhydrylsemicarbazone (IX). ...
