摘要
Mild and convenient methods for the high yielding ring-expansion substitution reactions of 1,3-dithiolanes and 1,3-dithianes generated from different aryl methyl ketones using different electrophilic reagents are reported. In this study, facile preparations of monohalo-, -cyano-, -azido-, -thiocyanato-1,4-dithiins and -1,4-dithiepins are described. A general mechanism is also proposed for the reactions described in this article. ((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005).
