by the dimerization of 3 and 9, respectively. The trapping reaction was studied in details; on one hand, bromo-2,3-dihydro-1H-phosphole oxides (6-1 and 6-2) were pointed out as the intermediates, on the other hand, the trapping reaction was optimized. Bri- dged P-heterocycles 4, 5, 10, and 11 were tested in the fragmentation-related phosphorylation of methanol. Hydrogenation of phosphanorbornenes 4
使用 1-phenyl-2-methyl-2,5-dihydro-1H-phospholeoxide (1) 和 1-cyclohexyl-3-methyl-2 合成了新型 7-phosphanorbornene 衍生物,例如 4、5、10 和 11 ,5-二氢-1H-氧化磷(7)为起始原料。产物 4 和 10 是通过用 N-苯基马来酰亚胺捕获相应的氧化磷中间体(分别为 3 和 9)制备的,而 5 和 11 分别通过 3 和 9 的二聚反应得到。详细研究了捕集反应;一方面,溴-2,3-二氢-1H-磷氧化物(6-1和6-2)被指出为中间体,另一方面,优化了捕集反应。桥接的 P-杂环 4、5、10 和 11 在甲醇的碎片相关磷酸化中进行了测试。磷降冰片烯 4 和 5 的氢化导致相应的磷降冰片烷(分别为 12 和 14)和还原型逆环加成。© 2005 Wiley Periodicals, Inc
