    • A process for preparing carboxylic acid esters of of the formulaX--(COOCH.sub.2 A).sub.nwherein A is the residue of a substituted or unsubstituted 3- or 4-benzocyclobutene compound, X is an n-valent organic bridging group, and n is 2,3, or 4, comprises reacting a substituted or unsubstituted 3- or 4-hydroxymethylbenzocyclobutene compound with a compound of the formula X--(COY).sub.n, wherein X is an n-valent organic bridging group and Y is Cl or Br. Esters of inorganic acids of the formulaX'(OCH.sub.2 A).sub.nwherein X' is a residue of an inorganic acid halide, n is 2 or 3, and A is the residue of a substituted or unsubstituted 3- or 4-benzocyclobutene compound, are prepared by reacting an inorganic halide of the formula X'Y.sub.n, wherein Y is Br or Cl, with a substituted or unsubstituted 3- or 4-hydroxymethylbenzocyclobutene compound. Biscarbonates of the formula X"[OC(.dbd.O)CH.sub.2 A].sub.2 wherein X" is the residue of a diphenol are prepared by reaction between a bis(halocarbonyl) compound of the formula X"[OC(.dbd.O)Y].sub.2, wherein Y is Cl or Br, and a substituted or unsubstituted 3- or 4-hydroxymethylbenzocyclobutene compound. The resulting esters are useful for making resins.
    • 一种制备式X-(COOCH 2 A)n的羧酸酯的方法,其中A是取代或未取代的3-或4-苯并环丁烯化合物的残基,X是n价有机桥基,n是2, 3或4包括使取代或未取代的3-或4-羟甲基苯并环丁烯化合物与式X-(COY)n的化合物反应,其中X为n价有机桥基,Y为Cl或Br。 式X'(OCH 2 A)n的无机酸的酯,其中X'为无机酰卤的残基,n为2或3,A为取代或未取代的3-或4-苯并环丁烯化合物的残基,为 通过使式X'Yn的无机卤化物(其中Y是Br或Cl)与取代或未取代的3-或4-羟甲基苯并环丁烯化合物反应制备。 式X“[OC(= O)CH 2 A] 2的双碳酸酯,其中X”是二酚的残基,通过式X“[OC(= O)Y ] 2,其中Y是Cl或Br,以及取代或未取代的3-或4-羟甲基苯并环丁烯化合物。 所得的酯可用于制备树脂。
