Contra-Thermodynamic Positional Isomerization of Olefins
Zhao, Kuo,Knowles, Robert R.
supporting information, p. 137 - 144 (2022/01/19)
A light-driven method for the contra-thermodynamic positional isomerization of olefins is described. In this work, stepwise PCET activation of a more substituted and more thermodynamically stable olefin substrate is mediated by an excited-state oxidant an
Ketone methylenation using the Tebbe and Wittig reagents - A comparison
Pine,Shen,Hoang
, p. 165 - 167 (2007/10/02)
Ketone methylenation has been accomplished using the Tebbe and the Wittig reagents. Comparison of the two reagents for a variety of ketones shows that the Tebbe reagent gives better product yields than the Wittig reagent. This is particularly important when the ketone substrate is hindered. It is also noted that the Tebbe reaction accomplishes methylenation in a non-basic medium, thus racemization does not take place on substrates with enolizable chiral centers.
Rhodium-catalyzed C-C coupling reactions involving ring opening of strained molecules. II. Addition to olefins and aromatic substitution
Chiusoli, Gian Paolo,Costa, Mirco,Melli, Luca
, p. 495 - 506 (2007/10/02)
Rhodium-catalyzed C-C coupling reactions, involving ring opening of strained molecules, have been studied using diphenylmethylenecyclopropanes as models.It has been established that, as rhodium takes control of the ring opening process, activated olefins
