A facile synthesis of vinyl and allylic 2,2,2-trifluoroethyl phosphonates
Kiddle, James J.,Davis, Ashley A.,Rosen, Jennifer J.
, p. 681 - 684 (1999)
Condensation of several representative aldehydes with the anion derived from tetrakis(2,2,2-trifluoroethyl) methylenediphosphonate, a new Wadsworth-Emmons reagent, afforded (Z)-vinyl phosphonates in good yields. The latter, when treated with a catalytic amount of potassium tert-butoxide in DMSO isomerized to the corresponding (E)-allylic phosphonates, which produce E,Z-dienes when reacted with a second aldehyde.
Regio- and stereoselective hydrosilylation of 1,3-enynes catalyzed by palladium
Zhou, Hui,Moberg, Christina
supporting information, p. 1444 - 1447 (2013/06/27)
In the presence of Pd(0) and a phosphine, hydrosilylation of 1,3-enynes with Me2SiHCl proceeds to yield dienylsilanes with the silicon function added to the internal alkyne carbon atom and with (E)-configuration of newly formed olefinic bond. The silanols isolated after hydrolysis of the primarily obtained products serve as precursors to conjugated dienes with different substitution patterns.
Synthesis of stilbenes promoted by the mixture of zinc and iron powder
Zhanga, Zhiying,Xieb, Yuanyuan,Yua, Xiaochun
experimental part, p. 140 - 142 (2009/10/15)
Stilbenes have been synthesised by a one-pot reaction of aldehydes with benzyl bromide. The reaction was promoted by both triphenylphosphine and the mixture of zinc and iron together in sealed tube. The yields ranged from moderate to excellent.
