The organocopper route from (2-propynylidene)morpholinium triflates to morpholinoallenes, 1-morpholino-1,3-butadienes, and 2-morpholino-1,3-butadienes

Organocopper reagents undergo conjugate addition to (1,3-diphenyl- and (1-methyl-3-phenyl-2-propynylidene)morpholinium triflates 1a and 1b. The resulting morpholinoallenes can be isolated if the allenic unit bears no CH substituent. Allenes bearing a Rsu
