Mercuration of selenophenes

Kinetic studies on the mercuration of selenophene and its derivatives have also been reported.170... 

Rate constants for the mercuration of selenophene and its 2-bromo, 2-carboethoxy, 2-acetyl, and 2-nitro derivatives under the conditions employed by Motoyama et al.,121 have been determined at various temperatures by Yur ev and his co-workers.304 The selenophene derivatives were mercurated from 1.5 to 3 times more rapidly than the corresponding thiophene derivatives. A straight line is obtained in the Hammett plot with ap+ constants, with a p value of — 5.7 at 25°.
