A New Synthetic Approach to Boron Triisothiocyanate-Tertiary Amine Adducts and Related Species

Abstract
The reaction of the adduct BDMA.BC13 (BDMA = N.N dimethylbenzylamine) with KNCS in refluxing, toluene, with tetraglyme added, was found as a very convenient route to BDMA.B(NCS)3. Further, according to the stoichiometry, either mixed species BDMA.BC1n(NCS)3-n(n = 1,2) or K+|B(NCS)4|, were also obtained. The same reaction was applied to KF and KNCO as well as to other tertiary alkylamines.
