Structural features of di(1-adamantyl)benzylphosphane complexes of Cu(I) and Ag(I)
The sterically bulky di(1-adamantyl)benzylphosphane (L) reacts with the copper(I) compounds, CuX (X = Cl, Br, I and SCN), in a 1:1 ratio to give the salts CuXL. Single crystal X-ray structures for X = Cl, Br and SCN, show that the complexes exist as dimeric species of the type [Cu2X2L2] with the X groups bridging to give each copper a distorted trigonal-planar coordination geometry with a ?PX2? donor site. When [Cu(CH3CN)4]BF4reacts with L in a 1:2 ratio, the two-coordinated complex [CuL2]BF4was formed which has a P?Cu?P angle of 169.46(6), reflecting the influence of the adamantyl groups. The silver(I) 1:2 compound, [AgClL2], has a ?ClP2? donor set with a distorted P?Ag?P bond angle of about 149.02(5). The reduced coordination numbers, irregular structures and distortions of selected angles are a result of the steric bulk (large cone angle) of L. Some of these structural features may also assist in understanding why Pd(0) complexes of L are effective catalysts for the Sonogashira coupling reactions of arylchlorides and alkynes.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 1111-67-7
