Synthesis and reactivity of α-cationic phosphines: the effect of imidazolinium and amidinium substituents

Abstract: Mono- and dicationic phosphines have been synthesized through the reaction of chloroimidazolinium or chloroamidinium salts with secondary or primary phosphines respectively. The resulting ligands, which depict a significantly reduced donor ability compared with their neutral analogues, have been used to design Pt(II) and Au(I) complexes that effectively catalyse the hydroarylation of alkynes.

“…The most general method used to prepare carbeniophosphines consists of the condensation of secondary diaryl or dialkyl phosphines with chloro‐substituted onium cations (Scheme ) ,. This strategy gives direct access in good yields to imidazolinio‐ 1 , pyridinio‐ 2 , cyclopropenio‐ 3 , and formamidiniophosphines 4 , respectively. Owing to the availability of both precursors, the stereoelectronic properties of α‐cationic phosphines 1 – 4 can be widely tuned.…”

“…Owing to the availability of both precursors, the stereoelectronic properties of α‐cationic phosphines 1 – 4 can be widely tuned. This condensation strategy can also be applied to the preparation of α‐dicationic phosphines by reacting primary phosphines with two equivalents of chlorocarbenium salts in the presence of a strong base …”
