A rapid and efficient method for 1,3-dithiolane synthesis
摘要:
A mild, efficient and solvent-free protocol for conversion of aldehydes and ketones into their corresponding 1,3-dithiolanes using 1,2-ethanedithiol in the presence of a catalytic amount of SnCl(2)(.)2H(2)O is reported. (c) 2006 Elsevier Ltd. All rights reserved.
