1.A study was made of the action of lithium metal and skeletal nickel on benzo-[b]-naphtho-[2,3-d]-thiophene, and of Grignard reagents on 7-keto-7,8,9,10-tetrahydrobenzo-[b]-naphtho-[2,3-d]-thiophene.2.The action of lithium metal on benzo-[b]-naphtho-[2,3-d]-thiophene leads to the elimination of the sulfur atom and the formation ofß-phenylnaphthalene.3.A number of new 7-substituted derivatives of benzo-[b]-naphtho-[2,3-d]-thiophene, and specifically 7-methyl-, 7-propyl-, 7-butyl-, 7-phenyl, and 7-benzylbenzo-[b]-naphtho-[2,3-d]-thiophene, were obtained by the reaction of Grignard reagent with 7-keto-7,8,9,10-tetrahydrobenzo-[b]-naphtho-[2,3-d]-thiophene and subsequent dehydrogenation of the 7-substituted derivatives of 9,10-dihydrobenzo-[b]-naphtho-[2,3-d]-thiophene with selenium powder. |
