Diethyl squarate: 3-Cyclobutene-1,2-dione, 3,4-diethoxy

Dehmlow49) found that the photochemical extrusion of carbon monoxide from the cyclobutene dione system is possible as exemplified by the conversion of diethyl squarate (43) to diethoxy cyclopropenone (44) ... [Pg.16]

Diethoxy-3-cyclobutene-1,2-dione is commercially available from Aldrich Chemical Company, Inc. Caution This substance was found to cause severe skin rashes, and extreme care should be exercised in handling it.. The dimethoxy analog appears to be safer. Diethyl squarate has the following spectral properties IR (neat) cm- 1830, 1741, and 1609 H NMR (CDCI3, 300 MHz) 8 1.47 (t, 6 H. J = 2.9), 4.47 (q, 4 H, J = 7.1). [Pg.222]
