Synthesis, structure determination and catalytic activity of (+)-cis-[dicarbonyl-μ-chloro-μ-[5β-methyl-2α-(1-methylethyl)cyclohexanethiolato]]-bis[tris(1,1-dimethylethyl)arsine]dirhodium
摘要:
The title compound, 5, which is the first dirhodium complex to contain both arsenic and a chiral substituent, has been synthesized from [Rh(CO)2]2(mu-Cl)2, As((t)Bu)3 and (+)-(neomenthanethio)trimethylsilane. The complex was found to catalyze the hydrogenation of methyl N-acetamidocinnamate, albeit with low enantioselectivity. X-Ray diffraction studies revealed that 5 exists in the crystal as a pair of epimers.
