Reactions of 9-phenylthioxanthene 10-oxide (1) with a variety of Grignard reagents afforded 9-substituted 9-phenylthioxanthenes (2). Similarly, organolithiums reacted with the sulfoxide 1 to give the corresponding thioxanthenes 2. The structures of 9-aryl

Reaction of 9-phenylthioxanthylium salt (1) with phenyl-lithium afforded eight compounds, 9-phenyl- (2), 9,9-diphenyl- (3). 3,9-diphenyl (4), 3,9,9-triphenyl- (5), and 4,9,9-triphenyl-thioxanthene (6), 9,9'-diphenyl-9,9'-bithioxanthenyl (7), thioxanthone (8), and 9,9'-diphenyldithioxanth-9-yl peroxide (9).Their structures were determined by comparison with the authentic samples.Six samples, (3)-(6), 2,9,9-triphenyl- (30), 9-(biphenyl-4-yl)-9-phenylthioxanthene (31) were independently synthesized in order to determine the structures of two pairs of positional isomers, 3,4, and 5,6.A radical mechanism contributed to the reaction of compound (1) with phenyl-lithium.
