Abstract

Heating of alkynyl propargyl selenides afforded a stereoisomeric mixture of 5,10-diselenadispiro[3.1.3.1]deca-1,7-dienes. The 1,3-diselenetane rings of the products caused cycloreversion by heating to generate 2-methylene-3-cyclobutene-1-selones and the selones were trapped with diene to give [4+2] cycloadducts.
