Tandem base-free synthesis of β-hydroxy sulphides under ultrasound irradiation
Rongalite promotes cleavage of diaryl disulphides generating the corresponding thiolate species in situ which then undergo facile ring-opening of epoxides in a regioselective manner under ultrasound irradiation, affording β-hydroxy sulphides in good to ex
Rongalite promoted highly regioselective synthesis of β-hydroxy sulfides by ring opening of epoxides with disulfides
Rongalite promotes cleavage of disulfides generating thiolate anions that then undergo facile ring opening of epoxides in the presence of K2CO3 to afford α-addition products 3 with good to excellent yields. The important f
Polystyrene-supported 1,5,7-triazabicyclo[4.4.0]dec-5-ene as an efficient and reusable catalyst for the thiolysis of 1,2-epoxides under solvent-free conditions
Polystyrene-supported 1,5,7-triazabicyclo[4.4.0]dec-5-ene (PS-TBD) is an effective basic catalyst for the thiolysis of the 1,2-epoxides 1a-e by the aryl- and alkyl-substituted thiols 2A-E under solvent-free conditions while its activity is remarkably redu
