摘要：

The molecular structure of the 2-methylallyl species Ru((R)-binap)(eta(3)-Me-allyl)(2) (3) was established by X-ray crystallography of a crystal of 3a, the asymmetric unit of which is composed of half of a molecule of 3 and half of a (R)-(+)-2,2'-bis(-diphenylphosphinoyl)-1,1'-binaphthyl(binap dioxide) molecule, co-crystallized with two disordered deuterobenzenes; crystals of 3a are tetragonal, space group I422, with Z = 8, a = 21.344(1) Angstrom and c = 36.453(2) A. The structure was solved by direct methods and refined by full-matrix least-squares procedures to R = 0.034 and R-w = 0.032 for 3431 reflections with I greater than or equal to 3 sigma(I). The 1,4-bis(diphenylphosphino)butane (dppb) analogue (2) of 3 was also prepared and characterized by H-1 and P-31{H-1}-NMR spectroscopy and elemental analysis, and the reactivities of 2 and 3 toward halogen acids are discussed.
