New Advances in Chemical Research, May 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic and spectroscopic. An article , which mentions Quality Control of (S)-Propane-1,2-diol, molecular formula is C3H8O2. The compound – (S)-Propane-1,2-diol played an important role in people’s production and life., Quality Control of (S)-Propane-1,2-diol
Complexation of (4S,9S)-4,9-diethyl-2,11-dioxa-5,8-diaza-1lambda 5-phosphatricyclo[6.3.0.01.5]undecane (1) and 3,3,8,8-tetramethyl-1,6-dioxa-4,9-diaza-5lambda 5-phosphaspiro[4,4]nonane (2) with [Rh(CO)2Cl]2; 2,3,7,8-dibenzo-1,6-dioxa-4,9-diaza-5lambda 5-phosphaspiro-[4,4]nonane (3) with [Rh(CO)2Cl]2 and [MCl2(COD)] (M = Pd, Pt); (2S,7S)-2,7-dimethyl-1,4,6,9-tetraoxa-5lambda 5-phosphaspiro[4,4]nonane (4) with [Rh(CO)2Cl]2 and [PdCl2(COD)] has been studied. The products have been characterized by 1H-, 2H-, 13C-, 31P-NMR, IR spectroscopy, laser desorption mass spectrometry and X-ray photoelectron spectroscopy. A possible mechanism for hydrophosphoranes complexation is discussed. A correlation between Lewis basicity and coordination activity has been found for ligands 1-3. Phosphorane 4 was shown to coordinate by means of the P(III)-tautomer.
