Dialkylselenaethenylboranes reacted with iodonium salts in the presence of a catalytic amount of Pd(PPh3)4 and NEt3 at room temperature to provide dialkylselenaalkenes with retention of configuration.

We were tried to use Na2CO3 as base according to method reported previously,4 It was found that a trace amount of 1,1-dialkylselenaalkenes were formed with the migration of an alkylselenyl group.
