- Abstract
Diazeniumdiolates (RN(O)NO−, R=Et, Et2N) react in an R-dependent manner with Wilkinson's catalyst to give either a chelated square-planar complex, Rh( η2-O2N2Et)(PPh3)2, 1, for R=Et, or with initial chelation followed by reductive nitrosylation to give Rh(NO)(PPh3)3, in the case of R=Et2N. Methyl iodide oxidatively adds to 1 to give RhIMe( η2-O2N2Et)(PPh3)2, 2, as a pair of isomers a, major, and b, minor. Both 1 and 2a have been structurally characterized by single-crystal X-ray diffraction.
