摘要： Precatalysts of formula I and IV, and processes for the functionalization of SP2-carbons using the same are described herein. The precatalysts comprise a fluoroborate salt protected intramolecular frustrated lewis pair (FLP). The precatalysts are bench stable with improved stability towards moisture and/or air. The precatalysts can be used to generate in situ the corresponding FLP catalyst.

摘要： Precatalysts and catalytic processes for the functionalization of sp2-carbons using the precatalysts are described herein. The precatalysts comprise an intramolecular Frustrated Lewis Pair (FLP) that is generated in situ from the corresponding precatalyst fluoroborate salts. The precatalyst fluoroborate salts are deprotected in situ to generate catalysts including intramolecular FLPs for the dehydrogenative borylation of alkenes, arenes and heteroarenes. The catalytic process comprises contacting a precatalyst, a functionalization reagent; and a substrate comprising a sp2-H carbon, under conditions to provide a substrate comprising a functionalized sp2 carbon.

摘要： Catalysts for the reduction of CO2 are described herein. More specifically, catalysts of Formula I and Formula II: wherein LB is a Lewis base; LA is a Lewis acid; R1 is selected from hydrogen, alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, phenyl and substituted phenyl; and R9 and R10 are independently selected from alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, phenyl and substituted phenyl; are described. A process for the production of methanol from CO2 using such catalysts is also described.
