Abstract

An unsymmetrical PCN palladium pincer complex 2-{(E)-{{(R)-1-[(1R,5S,6R)-3,3-dimethyl-2,4,7-trioxabicyclo[3.3.0]octan-6-yl]ethyl}imino}methyl}-6-{[(diphenylphosphino)oxy] phenyl}palladium(II) chloride based on an iminophosphinite ligand bearing two fused five-membered cycles, one of which containing a THF ring, was prepared in an eight-reaction sequence from a sustainable and enantiopure starting material, isosorbide, in a 20% overall yield.
