Olefin metatheses in metal coordination spheres: novel trans-spanning bidentate and facially-spanning tridentate macrocyclic phosphine complexes
Abstract
The title reaction is applied to square-planar rhodium and
platinum complexes with trans
PPh2(CH2)6CHCH2
ligands, and square-planar platinum or octahedral tungsten complexes with
trans or facial
PPh[(CH2)6CH
CH2]2
ligands. Ring-closing (poly)macrocyclizations occur.
