, p. 2120 - 2123 (2007/10/02)

The reaction of various phenols with 2-ethoxy-1,3-dithiolane proceeded smoothly in the presence of BF3*Et2O to afford 1,3-dithiolan-2-ylated phenols, which were readily hydrolyzed to the corresponding aldehydes.This process was also extended to N,N-dimethylaniline and indole.
