    Abstract The complex Ir(CH 3 ) (CO) (CF 3 SO 3 ) 2 (dppe) ( 1 ) has been synthesized from the reaction of Ir(CH 3 )I 2 (CO) (dppe) and silver triflate. Methane and IrH(CO) (CF 3 SO 3 ) 2 (dppe) ( 2 ) are formed when a methylene chloride solution of 1 is placed under 760 torr dihydrogen. Conductivity studies indicate that methylene chloride solutions of complexes 1 and 2 are weak electrolytes and only

  • Oxidative addition of catecholborane to IrX(CO)(dppe) complexes
    作者:Brian P. Cleary、Richard Eisenberg
    DOI:10.1021/om00010a017
    日期:1995.10
    The oxidative addition of catecholborane (1,3,2-benzodioxaborole) to the Ir(I) cis-phosphine complexes IrX(CO)(dppe) (X = Br, I, H, BO2C6H4; dppe = 1,2-bis(diphenylphosphino)ethane) has been found to proceed stereoselectively under kinetic control. Of the four complexes that can be formed by cis oxidative addition of the B-H bond to IrBr(CO)(dppe), the one having hydride trans to phosphorus and boron trans to bromide is formed in >99% yield while addition to IrI(CO)(dppe) occurs similarly but with only 90% stereoselectivity. Isomerization of the initially formed diastereomers to thermodynamically less stable diastereomers which display hydride trans to halide and boron trans to phosphorus occurs after 1 day. The mechanism for the isomerism for X = Br has been determined to proceed via reductive elimination/oxidative addition processes. The oxidative addition reactions of catecholborane to [IrH(CO)(dppe)] and [Ir(BO2C6H4)(CO)(dppe)], generated from IrH3(CO)(dppe) and IrH2(BO2C6H4)(CO)(dppe), respectively, also occur in a cis fashion with 99% stereoselectivity yielding Ir(III) products with hydride trans to CO and boron trans to phosphorus. The observed stereoselectivity for catecholborane addition to IrX(CO)(dppe) (X = Br, I) is reversed with respect to addition to IrX(CO)(dppe) (X = H, BO2C6H4) and is accounted for by electronic factors involving the pi-basicity of the halide ligands.
