Palladium-catalyzed coupling of (1,3-butadiynyl)amines with aryl and vinyl iodides
Loffler,Himbert
, p. 232 - 233 (2007/10/02)
4-Aryl, 4-heteroaryl- and 4-vinyl substituted (1,3-butadiynyl)-amines 7 and 8 are prepared in a one-pot synthesis by the successive treatment of the (3,4,4-trichloro-3-buten-1-ynyl)amines 1 with two equivalents of butyllithium and zinc chloride and by the palladium-catalyzed cross-coupling of the resulting aminobutadiynylzinc chlorides 4 with alkenyl, aryl and heteroaryl iodides, respectively.
A New Pathway to (4-Aryl-1,3-butadiynyl)amines
Loeffler, Achim,Himbert, Gerhard
, p. 125 - 126 (2007/10/02)
(4-Aryl-1,3-butadiynyl)amines 5 are prepared in a two-step synthesis: Palladium(II) catalyzed cross-coupling of arylacetylenes 1 and 2-bromo-1,1-dichloroethene (2) furnishes the 4-aryl-1,1-dichloro-1-buten-3-ynes 3, which are transformed into 5 by two equ
