The cycloaddition of N-chlorosulfonyl-isocyanate with isoprene, butadiene and a polyolefin as well as the reaction of ketenes with some bis-azomethines were investigated. Suitably substituted bis-azomethines could be separated in the rac. and the meso-form. The reactivity of the azetidinones towards hydrolysis and hydrogenation was tested. Attempts to polymerise 4-vinyl-azetidin-2-one, polyazetidinone
研究了N-氯磺酰基异氰酸酯与异戊二烯,丁二烯和聚烯烃的环加成反应,以及乙烯酮与一些双偶氮甲胺的反应。适当取代的双偶氮甲亚胺可以在rac中分离。和介观形式。测试了氮杂环丁酮对水解和氢化的反应性。尝试聚合4-乙烯基-氮杂环丁烷-2-酮,聚氮杂环丁酮和N-取代的双氮杂环丁酮以得到交联的聚-β-酰胺是不成功的。
