  • Use of pnictogenium compounds in carbon-carbon bond formation
    Patent number: 11254650
    Abstract: A method of synthesizing a reaction product of the formula R3-R4 by reacting a pnictogenium salt of the formula including a phosphonium salt of the formula with a Lewis acid in the presence of a nucleophile. The reaction products can then be isolated for use. R1 and R2 are individually selected from the group consisting of hydrogen, alkyl, heteroalkyl, aryl, heteroaryl, aralkyl, alkoxy, amino, and organosilyl. R3 and R4 are individually selected from the group consisting of optionally substituted monocyclic or polycyclic heteroaromatic moieties, optionally substituted monocyclic or polycyclic heteroaliphatic moieties, and optionally substituted linear or branched heteroaliphatic moieties. R1 or R2 optionally forms a covalent bond with R3 or R4. X is an anion.
