Protected acrolein equivalent. Reacts with Grignard reagents (CuBr catalysis) to give predominantly (Z)-enol ethers which can be hydrolyzed to 3-substituted propionaldehydes: Tetrahedron Lett., 3833 (1975). The (E)-enol ether is formed selectively with a Ni(II)-phosphine catalyst: Chem. Lett., 351 (1985).

Heck coupling (see Palladium(II)­ acetate, 10516) occurs with aryl or vinyl bromides in the presence of morpholine or piperidine: J. Org. Chem., 46, 1061 (1981); J. Chem. Soc., Perkin 1, 2597 (1987):
