2,11-Dithia[3.3.1]paracyclophane, (I), and 2,11-dithia[3.3.2]paracyclophane, (II)
摘要:
In the title compounds [C23H22S2, (I), and C24H24S2, (II)], the thio-bridging chains on either side of the benzene ring (A) are oriented anti to each other. Ring A is located nearly perpendicular to the other benzene rings (B and B') to give a short contact between an H atom of ring A and the center of ring B (B'). The thio-bridging moieties in (I) and (II) seem to be almost strain-free.
