Data are presented for reduction of bibenzyl, diphenylmethane, and diphenyl sulfide by H/sub 2/S which indicate that the chemical reactions are of more than one type. The H/sub 2/S is more effective in the hydrocracking of bibenzyl to benzene and toluene than is H/sub 2/. H/sub 2/S also appears to be a hydrogen donor and forms aromatic-sulfur bonds which implies that the sulfur can attack aromatic rings. Various reactions are proposed for the formation of sulfur which catalyzes the conversion of diphenylmethane. (BLM)
