Description

1. INTRODUCTION Chiral palladium complexes of various types are widely used in modern asymmetric synthesis, the goal of which is to obtain enantiopure compounds. Cyclopalladated complexes (CPCs) form a special group of compounds with a [sigma]-connection palladium-carbon [1]. These complexes show reasonably high activity and thermal stability. Chiral CPCs are very successfully used in asymmetric synthesis, both as the original matrix [2-7] and as catalysts [8-12]. They have been used in NMR studies as shifting reagents [13-15] and as effective resolution agents [16-18]. This is especially significant for obtaining enantiopure phosphines, which are efficient ligands for asymmetric catalysis of transition metal complexes. Currently, the CPCs are received with different types of chirality [1]. The compounds of a variety of classes have been tested for their ability to become ligands for CPCs. However, the synthetic accessibility of chiral ligands remains an important problem.
