Deuteration and Spectroscopic Studies of (3)-1,2-B9C2H12(-), (3)-1,7-B9C2H12(-) and (3)-1,2-B9C2H13.
Abstract
The deuterium exchange reactions of (3)-1,2-B9C2H12(-), (3)-1,7-B9C2H12(-), and (3)-1,2-B9C2H13 were studied using 11B nmr and infrared spectroscopy. On the basis of these measurements, and 13C nmr spectral measurements probable structures for these compounds are proposed. It has been found that some terminal hydrogen exchange takes place under acidic but not basic conditions. A total assignment of the 11B nmr spectrum (80.5 MHz) of (3)-1,2-B9C2H12(-) is proposed on the basis of the deuteration studies and 11B nmr data obtained from 6-C6H5-(3)-1,2-B9C2H11(-) and 9,12-Br2-(3)-1,2-B9C2H10(-). An assignment of the 11B nmr spectrum of (3)-1,2-B9C2H13 is also proposed. (Author)
