The first, a direct metalation strategy failed to produce chelating complexes, instead generating monodentate NHC-Ir species.
Spectral data concerning these compounds, as well as our initial efforts toward metalation of the polymer-supported ligand, will be presented.
Following the early contributions of Beak, Meyers, and many others, Snieckus has developed the directed ortho metalation
reaction to its current status as a key concept in aromatic chemistry.
Intercepting normal metalation
reactions may be a way to control metalloprotein activity.
Branching can be imparted to the typical anionic polymerization by thermal heating multi-functional monomers, metalation
grafting techniques, and post-polymerization linking reactions.
The copolymer was synthesized from PPTA and epoxy via metalation
of PPTA in a solution of sodium methylsulfinylcarbanion in dimethylsulfoxide.
Victor Snieckus, FCIC, holder of the Monsanto Industrial Research Chair, is a world-renowned researcher in directed ortho metalation
