Abstract
The process of nucleophilic substitution of the phenyliodonium substituent in the [1-B10H9IPh]– anion with primary amines in organic nitriles has been studied. It has been shown that the reaction proceeds with the formation of a mixture of products, namely, 1-monoalkylammonio-closo-decaborate and the corresponding amidine, which is formed when an amine molecule is added to the nitrile. The resulting products have been characterized by 1H, 11B, 13C NMR spectroscopies, IR absorption spectroscopy, and high-resolution ESI mass spectroscopy.
