And the article contained the following:

Phosphine and bidentate N-N ligands inhibit the Alder-ene-type cycloisomerization of enynes catalyzed by Pt(II) and favor the alkoxycyclization process. The enantioselective Pt(II)-catalyzed alkoxycyclization has been studied in the presence of chiral mono- and bidentate phosphines, as well as chiral bidentate N-N ligands. Modest levels of enantioselection (up to 50% ee) have been obtained with Tol-BINAP as ligand. The alkoxycyclizations with a catalyst formed from [Au(L)Cl]/AgX proceed more readily, and up to 94% ee’s have been obtained using [(AuCl)2(Tol-BINAP)] (1) as the precatalyst. X-ray crystal structures of Au(I) complexes 1 and chloro-(R)-2-(tert-butylsulfenyl)-1-(diphenylphosphino)ferrocene gold(I) show the AuCl fragments monocoordinated with the P centers of the chiral phosphine ligands.

A femtosecond fluorescence upconversion study of [2,2′-bipyridyl]-3,3′-diamine (BP(NH2)2), in liquid solution, is reported. It is concluded that photoexcited BP(NH2)2 undergoes a branched intramol. double proton transfer reaction comprising two trajectories: (a) ultrafast double proton transfer (<100 fs) followed by twisting (∼250 fs); (b) a combined process of double proton transfer and twisting, with an overall reaction time of ∼250 fs. Picosecond transient fluorescence is attributed to vibrational cooling in the excited product state. The lifetime of ∼10 ps of the tautomer product state is indicative of conical intersection of the product- and ground-state potential energy surfaces.
