25.有機分子間の水素異動過程における触媒効果(II) : trans-スチルベンの水素化における金属・炭素質・水素供与体の相互作用

抄録

Hydrogen transfer from tetralin to trans-stilbene at 380℃ was promoted by carbon materials such as activated carbon, carbon black and fullerene-rich soot. They decreased selectivities for 1, 2-diphenylethyl radical stabilization rather than increased bibenzyl yields. Its addition to the aromatic nucleus of trans-stilbene was promoted on the surfaces of the above carbon materials. With metal oxides as catalyst, tetralin hydrogens were also consumed in the reduction of the metal oxides to give little higher bibenzyl yields than without catalyst.
