Abstract
Abstract The coupling reaction of 1-tributylstannylthianthrene (5) and 2- tributylstannylthianthrene (7) in the presence of copper catalysts at rt afforded the thianthrene dimer 1, 1′-bithianthrene (3), 2, 2′-bithianthrene (8), and 1, 2′-dithianthrene (9) in high yields. Also we obtained thianthrene oxide dimer (R, R)(S, S)-1-(10-S- monoxythianthrene-1-yl) thianthrene-10-S-monoxide (12) and (R, S)(S, R)-1-(10-S- ...
