Synthesis and Molecular Structure of a Chiral Bipyridine-Menthol Ether

Synthesis of substituted (N,C) and (N,C,C) Au(iii) complexes: the influence of sterics and electronics on cyclometalation reactions

“…84 The N1-C1-O5 angle in 2m-Au(OAc F ) 2 is 114.51(18)°, being slightly smaller than the corresponding N-C-O(alkoxy) angles in reported crystal structures of non-coordinated pyridines, bipyridines or phenanthrolines with alkoxy substituents α to nitrogen (typically around 120°). 40,[84][85][86][87][88] The angle is similar to the N-C-O(alkoxy) angle in (N,C) Au(III) and Pd(II) complexes derived from 6,6′-dimethoxy-2,2′-bipyridine reported by Cinellu and co-workers. 40,84 The relatively small N-C-O(alkoxy) angle in 2m-Au(OAc F ) 2 , together with a Au1-O5 distance of 3.13 Å may hint at a weak interaction between the gold centre and the oxygen atom in the methoxy group.…”
