Stabilisation of monovalent palladium by tetra-aza macrocycles
Abstract
The single crystal X-ray structure of [Pd(1)](PF6)2·MeNO2[(1)= 1,4,8,11-tetramethyl-1,4,8,11-tetra-azacyclo-tetradecane] shows a square planar stereochemistry with an (R,S,R,S) conformation; electrochemical reduction at –1.65 V vs. Fc/Fc+(Fc = ferrocene) in MeCN affords a highly reactive d9 palladium(I) derivative.
