General Description
4-Cyanobenzophenone is a benzophenone derivative that can be prepared by treating 4-cyanobenzoyl chloride with benzene. Its reduction under electrochemical condition led to the formation of 4-t-butyl-benzophenone and 1-(4-cyanophenyl)-2,2-dimthyl-1-phenylpropan-1-ol. Its efficiency as triplet sensitizer for norbornadiene(N)→quadriciane(Q) and Q→N photoisomerization has been assessed.
