acid in benzene or toluene result in the formation of hydrogen-bonded adducts between the proton donor and the pendant pyridine or quinoline group. However, in a more polar solvent such as dichloromethane, there is spectral evidence for the proton transfer to the hydride to yield a dihydrogen complex. The protonation with CF3SO3H in CD2Cl2 occurs in a stepwise manner. In a first step, the pendant pyridine

Alkali and alkaline-earth metalcomplexes, and an Yb(II)-crown ether complexderivedfrom a 2-quinolyl-linked (borano-phosphinoyl)methane have been synthesized and structurally characterized. These complexes exhibit diversified structures in which the deprotonated (borano-phosphinoyl)methane ligand bonds to the metals in various coordination modes.

Reaction of 3 with 1 equiv of MN(SiMe3)2}2 (M = Sn, Pb) afforded the corresponding “open-box” 1,3-distannacyclobutane [Snμ2-C(iPr2P═S)(C9H6N-2)]2 (11) and [Pbμ2-C(iPr2P═S)(C9H6N-2)]2 (12), respectively. The structures of 3–6 and 9–12 have been determined by X-ray crystallography.
