Difenilcetena é um composto químico orgâni … Difenilcetena é um composto químico orgânico da família das cetenas. Difenilcetena, como a maioria da cetenas sunbstituídas é um óleo vermelho ou laranja a temperatura e pressão ambiente. A reação mais importante do difenil ceteno é a [2 + 2] cicloadição nas ligações múltiplas C-C, C-N, C-O e C-S.as ligações múltiplas C-C, C-N, C-O e C-S.
