THE PREPARATION OF B-METHYL DERIVATIVES OF C2B4H8; THE CORRELATION OF PROTON NMR CHEMICAL SHIFT MEASUREMENTS IN C2B4H8 DERIVATIVES BY EMPLOYING 'RING CURRENT' CONTRIBUTIONS.
Abstract
By the reaction of methylpentaborane with acetylene and 2-butyne, all of the B-methyl derivatives of 2,3-C2B4H8 and of 2,3-dimethyl-2,3-C2B4H6, respectively, were prepared. The proton nmr of the terminal substituents on boron are correlated by an empirical consideration of 'ring current' contributions. In this approach the relative magnitude, as well as the direction, of the chemical shifts can be reasonably predicted. (Author)
