Study of cyclic borinates obtained from piperidine- and piperazine alcohols by spectroscopic methods and X-ray crystallography
摘要:
A series of eleven new 2-aminoethyl- and 3-aminopropyl borinate derivatives with a coordinative N --> B bond has been synthesized by condensation reactions between piperidine-as well as piperazine alcohols and diphenylborinic acid. The products obtained are analogous to N-spiro compounds and bicyclic systems and have been characterized by spectroscopic methods and X-ray crystallography. Thereby the N --> B bond and the geometry of this new heterocyclic systems have been studied in more detail. (C) 1998 Elsevier Science S.A.
