By functionalizing the privileged biphenyl-2-ylphosphine with a basic amino group at the rarely explored 3′ position, the derived gold(I) complex possesses orthogonally positioned "push" and "pull" forces, which enable for the first time soft propargylic deprotonation and permit the bridging of a difference of >26 pKa units (in DMSO) between a propargylic hydrogen and a protonated tertiary aniline. The application of this design led to efficient isomerization of alkynes into versatile 1,3-dienes with synthetically useful scope under mild reaction conditions.

The reaction of [PhC=MBr3(dme)] (dme = 1,2-dimethoxyethane) with the hexafluoro-fert-butoxides LiJ. or KX [X = OC(CF3)2Me] afforded the benzylidyne complexes [PhC=MX3(dme)] (2a: M = W, 2b: M = Mo), which further
Hexafluoroisopropanol as a unique solvent for stereoselective lododesilylation of vinylsilanes
Ilardi, Elizabeth A.,Stivala, Craig E.,Zakarian, Armen
supporting information; experimental part, p. 1727 - 1730 (2009/04/10)
Stereoselective preparation of iodoalkenes from vinylsilanes is described. 1,1,1,3,3,3-Hexafluoroisopropanol serves as a unique solvent that ensures high yields and stereoselectivities in the iododesilylation of a variety of functionalized substrates.
Highly selective hydrogenation of multiple carbon-carbon bonds promoted by nickel(0) nanoparticles
Alonso, Francisco,Osante, I?aki,Yus, Miguel
, p. 93 - 102 (2007/10/03)
A new method for the highly stereoselective cis semihydrogenation of internal alkynes, semihydrogenation of terminal alkynes, reduction of dienes to alkenes, and reduction of alkynes and alkenes to alkanes is described based on in situ generated both Ni(0) nanoparticles and molecular hydrogen.
