4,4'-dibromo-, 4-bromo-, 4,4'-dichloro-, 4-chloro-, 4-methyl-, 4,4'-dimethyl-, 4-phenyl-, 4-carbomethoxyl-, 4-cyano-, 4-cyano-4'-methyl-, and 4,4'-dimethyldiphenyldiazomethane were studied by laser flash photolysis.Excitation of the diazo compounds at 308 nm produced the corresponding diarylcarbenes.The kinetics of the reaction of the substituted carbenes with alkanes and methanol were examined.Hydrogen abstraction rates are largely insensitive to ring substitution, while the methanol reaction is accelerated considerably by p-methyl substitution and retarded by a para electron-withdrawing substituent.

By spectral and chemical methods it was established that the photolysis of vacuum-treated solutions of 4-biphenylylphenyldiazomethane in benzene leads to the formation of 4-biphenylyldiphenylmethane, 4-biphenylylphenylcarbinol, and 4-biphenylyl phenyl ketone; in carbon tetrachloride 1,1,1,2,2,3-hexachloro-3-(4'-biphenylyl)-3-phenylpropane and 4-biphenylyl phenyl ketone are obtained.In unevacuated solutions 4-biphenylyl phenyl ketone is formed.By ESR, luminescence, and low-temperature spectrophotometry it was established that triplet 4-biphenylylphenylcarbene and also the radical products from the reaction of this compound with solvent ar e formed.A probable scheme for the reaction mechanism is given.
