Reactions of Some Boron Heterocycles with Pyrazole

Abstract

There exist three principal types of neutral heterocyclic pyrazole ( = Hpz) derivatives containing two four-coordinate annular boron atoms. The pyrazaboles of type 1 have been known for more than two decades. They contain the skeleton >B(mu-pz)2B< and almost 100 different B- and/or C-substituted derivatives have been described. Triply bridged pyrazaboles of type 2 with X=- OBRO- were accidentally discovered in recent studies on the interaction of boroxins, (-RBO-)3, with pyrazole, and only one additional representative of this type 2 (with X = SS) has since been reported. In addition, several dibora monocations of the structural type 2 where X = pz have been described.
