选定的卤代烷酮BX 1 X 2 X 3(X 1 = Cl或Br,X 2和X 3为= X 1或Ph),通常与乙炔(HCCH,BuCCH,PhCCH或取决于乙炔的性质,得到(2-卤代或2-苯基烯基)硼烷。产物的特征在于乙酰分解原脱硼,醇解及其红外光谱。用于不对称乙炔。展示了Markownikoff的添加;对于乙炔来说,空间反应过程是反式的,但据信是顺式的对于至少一些取代的乙炔。反应性随硼烷的高受体强度和乙炔的高亲核性而增加。与氢硼化相反,乙炔的氯硼化和有机硼化显然是热力学控制的过程。

A curable composition comprises (A) a polymer whose molecules have a main chain comprising carbon-carbon bonds and one or more isocyanatocarbonyl groups pendant to the main chain, the content of the isocyanatocarbonyl groups per polymer molecule being from 0.1 to 72.2% by weight, and (B) an active hydrogen atom-containing compound. Various polymers of the given type, including polymers having pendant isocyanatocarbonyl and/or isocyanato groups, are novel.
A functional polymer whose molecules have a main chain of carbon-carbon bonds and one or more pendant functional groups each appended to the main chain via a carbonyliminocarbonyl linkage, in which the or each functional group is chosen from fluorinated, aminotriazine, photosensitive, bicyclic and spiro structure-containing groups, and in which the content of the functional groups plus the carbonyliminocarbonyl linkages per molecule is from 0.1 to 99.9% by weight.
