Carbon-Sulfur Bond Cleavage in Methanesulfonate on Diorganotin Quinaldate Platform - Synthesis and Characterization of [(n-Bu2SnL)2SO4]

Chem Asian J. 2024 Feb 14:e202400013. doi: 10.1002/asia.202400013. Online ahead of print.ABSTRACTThe synthesis of mixed ligand di-n-butyltin complexes, [(n-Bu2SnL1-3)2SO4], 2-4 (HL1-3 = 2-quinoline/ 1-isoquinoline/ 4-methoxy-2-quinoline carboxylic acid) has been realized by reacting n-Bu2Sn(OMe)OSO2Me, 1a with the corresponding quinaldic acid under solvothermal conditions. The observed transformation of methane sulfonate to sulfate anion represents a rare example of C-S bond cleavage on the organotin scaffolds, n-Bu2Sn(L1-3)OSO2Me, which have been identified as en route intermediates by NMR and X-ray crystallography. Analogous reaction when extended with Me2Sn(OMe)OSO2Me, 1b and HL2 yields [(Me2Sn)2(L2)3(OSO2Me)], 5 as partially disproportionated product of Me2Sn(L2)OSO2Me. The solid-state structures of 2-5 reveal variable modes of coordination of the ligands to afford molecular and polymeric motifs.PMID:38353128 | DOI:10.1002/asia.202400013
