This articles reports preparation of and describes several reversible coordination reactions of borirenes and LBs, such as pyr, DMAP, IMe (saturated N,N-dimethyl NHC) and phoshpines.  IMe binds in a general fashion, unlike the N- and P-bases.  The borirenes are not very stable species, and decompose sometimes even under inert gases at RT.
