Ligand control of product stereochemistry in the photosubstitution reactions of rhodium(III) ammine complexes. The photoreactions of trans-[Rh(NH3)4(OH)Cl]+
Abstract
Ligand field photolysis of tran-[Rh(NH3)4(OH)Cl]+ results in concomitant photohydrolysis–photoisomerization (quantum yield = 0·21 mol einstein–1) to give cis-[Rh(NH3)4(OH)2]+, a stereochemical result in marked contrast to the analogous aquo species, cis- and trans-[Rh(NH3)4(H2O)Cl]2+, which undergo cis to trans but not trans to cis photoisomerization nor chloride photolabilization.
