Mono- and 1,3-disubstituted allenes were synthesized from the corresponding propargylamines via palladium-catalysed hydride-transfer reaction. In the current transformation, propargylic amines can be handled as allenyl anion equivalents and introduced into various electrophiles to be transformed into allenes under palladium-catalyzed conditions.
由相应的炔丙基胺经钯催化的氢化物转移反应合成了单-和1,3-二取代的烯丙基。在当前的转化中,炔丙基胺可以作为烯丙基阴离子当量处理,并引入各种亲电试剂中,以在钯催化的条件下转化为烯丙基。
