A process of producing a 1,1-cyclohexanedimethanol compound having a substituent group at the 2-position in which the step of producing a 1-hydroxymethyl-3-cyclohexene-1-carbaldehyde compound by Diels-Alder reaction of a &bgr;-substituted-&agr;,&bgr;-unsaturated aldehyde and a chain conjugated diene compound using an anhydrous tin (IV) halide catalyst is essential and a process of producing productive intermediates therefor. 1,1-Cyclohexanedimethanol compounds having a substituent group at least at the 2-position thereof obtained by the present invention are useful as a raw material for polyesters, unsaturated polyesters, alkyds, polyurethanes, epoxy resins, acrylic resins, etc. and as raw materials for functional organic compounds.
通过Diels-Alder反应,使用无水锡(IV)卤化物催化剂,生产1-羟甲基-3-环己烯-1-甲醛化合物的步骤是生产具有2-位置取代基的1,1-环己二甲醇化合物的过程中必不可少的,并且是生产这些有效中间体的过程。本发明得到的至少在2-位置具有取代基的1,1-环己二甲醇化合物可用作聚酯、不饱和聚酯、醇酸树脂、聚氨酯、环氧树脂、丙烯酸树脂等的原料,以及功能性有机化合物的原料。
