CpTiCl2, an Improved Titanocene(III) Catalyst in Organic Synthesis
Roldan-Molina, Esther,Padial, Natalia M.,Lezama, Luis,Oltra, J. Enrique
, p. 5997 - 6001 (2018/11/23)
Preparation, EPR analysis, and advantages in green organic chemistry of CpTiCl2, an improved single-electron transfer catalyst, are reported. Under mild conditions, this organometallic complex provides excellent yields of homoallylic and homopropargylic alcohols in Barbier-type allylation and propargylation reactions. Moreover, in the presence of a bidentate BOX ligand, Barbier-type cyclization reactions catalyzed by CpTiCl2 can be carried out in an enantioselective manner.

The general zinc-catalyzed allenylation of aldehydes and ketones with an allenyl boronate is presented. Preliminary mechanistic studies support a kinetically controlled process wherein, after a site-selective B/Zn exchange to generate a propargyl zinc int
Toluates: unexpectedly versatile reagents
Lam, Kevin,Markó, István E.
experimental part, p. 10930 - 10940 (2010/02/28)
The mechanism of the monoelectronic reduction of aromatic esters has been investigated. The unexpected synthetic utility of the toluate moiety in the deoxygenation of alcohols and the allylation of ketones is also reported. Finally, the use of aromatic esters as robust, though easily removable, protecting groups is depicted.
