Abstract
Abstract Reactions of the 1,5-cyclooctadiene complex [C8H12RhCl]2 with the potassium polypyrazolylborates K[H4−nBPzn] (Pz = pyrazolyl, n = 2, 3 and 4; Pz = 3,5-dimethylpyrazolyl, n = 2 and 3) in ethereal solvents give the corresponding complexes C8H12RhPznBH4−n as stable yellow solids. Reaction of [Rh(CO)2Cl]2 with potassium bis(pyrazolyl)borate in hexane gives yellow H2B(C3H3N2)2Rh- (CO)2, but similar reactions of [Rh(CO)2Cl]2 with the other polypyrazolylborates lead only to decomposition at room temperature. The tris- and tetrakis(pyrazolyl)borate rhodium 1,5-cyclooctadiene complexes all appear stereochemically non-rigid at room temperature.
