Abstract

A series of selenium and tellurium tricyclics (1,2) have been synthesized and their ⁷⁷Se and ¹²⁵Te NMR chemical shifts determined. Semiempirical MNDO-PM3 calculations on representative 1 and 2 have been used to characterize their folded and planar conformations. The results indicate a pronounced effect of the conformations on these chemical shifts.
