Abstract
Summary Flow thermolysis of 2-propynyl propiolate (5) at 580" afforded butatriene (6)(ca. 50%) and, as by-products, 4-methylene-2-cyclobuten-1-one (7), 2-ethynylpropenal (€ 9, l- penten-4-yn-3-one (9), 4-penten-2-ynal (10)(total ca. 10%), along with some propynal, acetylene, CO, and CO. In the same way, propiolic acid (1, 1-D2)-2-propynyl propiolate (11) led to (1, l-DJ-butatriene (12) and a little 4-((D,) rnethylene)-2-~ yclobuten-1-one (13). A ...
