In　this　investigation,　chiral　thiophosphoramide　3d　was　easily　prepared　from　chiral　(1R,2R)-1,2-diphenylethylenediamine　and　then　applied　as　an　efficient　chiral　ligand　in　the　catalytic　asymmetric　arylation　reactions　of　various　aromatic　aldehydes.　The　corresponding　diarylmethanol　products　were　produced　with　good　to　excellent　yields　(up　to　98%)　and　enantioselectivities　(up　to　94%).　The　recovery　of　chiral　ligand　3d　could　be　as　high　as　96%.　(C)　2016　Elsevier　Ltd.　All　rights　reserved.
