At a high temperature (>200°C), the reaction with alicyclic ketones is a very attractive application of DMC as a methoxycarbonylating agent. In particular, cyclopentanone and cyclohexanone, whose reactions with DMC (or (3 = diethylaminoethyl chokide hydrochloride (DEC)] and a base (K2CO3) yield adipic and pimelic dimethyl (or diethyl) esters, respectively (Scheme 4.18). ... [Pg.95]

Dimethylcarbonate [DMC, (CH30)2C0] is a versatile chemical substance, which has been used mainly as a carbonylating, methylating, or methoxycarbonylating agent. It can be effectively used as an environmentally benign substitute for phosgene in polycarbonates and isocyanates synthesis, and for dimethyl sulfate in various methylation reactions. ... [Pg.719]
