The progress in crystal structure determination of organometallic complexes and their organic synthons containing selenium and stereogenic phosphorus as heteroatoms

New Optically Active tert-Butylarylthiophosphinic Acids and Their Selenium Analogues as the Potential Synthons of Supramolecular Organometallic Complexes: Syntheses and Crystallographic Structure Determination

“…Here, we provide the information about the X-ray structures of phosphinothioic (1) and phosphinoselenoic (2) acids (Scheme 1). Phosphinothioic acids 1a and 1b and phosphinoselenoic acids 2a and 2b were synthesized according to our earlier described procedure [32,33]. It should be noted here that the X-ray structure of the levorotatory (S) enantiomer of tert-butylphenylphosphinoselenoic acid (2c) has been reported [34].…”
