Abstract
The synthesis of N,S-heterodisubstituted 1-(2′-pyridyl)-2-SR-1,2-closo-C2B10H10 compounds (R = Et, 2; R = iPr, 3) has been accomplished starting from 1-(2′-pyridyl)-1,2-closo-C2B10H11 (1), and their partial deboronation reaction leading to the structurally chiral [7-(2′-pyridyl)-8-SR-7,8-nido-C2B9H10]– derivatives (R = Et, [4]–; R = iPr, [5]–) has been studied.
