Tertiary α-cyanoamines served as the precusors of iminium ions in the presence of titanium tetrachloride. Various intramolecular nucleophiles, olefinic and acetylenic, were found to produce cyclized products. The influences of ring sizes and substitutions on the double bonds were also investigated.
在四氯化钛存在下,叔α-氰胺是亚胺离子的先驱物。发现各种分子内亲核试剂,烯属和炔属,可产生环化产物。还研究了环的大小和取代对双键的影响。
