An Unexpected Diboroxane: Crystal Structure of Me2HN · (CF3)2BOB(CF3)2 · NHMe2Dedicated to Professor Dieter Naumann on the Occasion of his 60th Birthday

Abstract

CF 3 ) 2 BNMe 2 (1) reacts at room temperature with water in a 2:1 ratio to form bis(dimethylamine)-tetrakis(trifluoromethyl)diboroxane Me 2 HN·(CF 3 ) 2 BOB(CF 3 ) 2 ·NHMe 2 (2), whereas a 1:1 ratio at Ϫ78°C had yielded HO(CF 3 ) 2 B·NHMe 2 (3). The constitution of 2 has been deduced from multinuclear NMR, IR and
