Abstract
The synthesis of several chiral tropocoronands (6 and 7) has been accomplished. These compounds have been shown to complex with various metals. Tropocoronands that have been synthesized include H2(TC-3,cyhex) through H2(TC-6,cyhex) (6) and H2(TC-3,diphen) through H2(TC-6,diphen) (7). The route is short and the tropocoronands are easily purified by chromatography or recrystallization. Two other groups have been incorporated into tropocoronands, H2(TC-3,binap) (9) and H2(TC-6,pent) (10).
