hexafluorophosphate

1. Visible light photoredox-catalyzed cascade cyclizations of α-bromochalcones or α-bromocinnamates with heteroarenes.
2. Enantioselective α-benzylation of aldehydes via photoredox organocatalysis.

[4,?4''-?Bis(tert-butyl)?-?2,?2''-?bipyridine]?bis[3,?5-?difluoro-?2-?[5-?(trifluoromethyl)?-?2-?pyridinyl]?phenyl]?iridium(III) hexafluorophosphate is commonly used as a catalyst in the synthesis of various compounds such as saturated N-?heterocycles from aldehydes, fosmidomycin analogue, and many more.

(Ir[dF(CF₃)ppy]₂(dtbpy))PF₆ is a cyclometalated iridium(III) complex that can be used in visible-light mediated photocatalytic organic transformations.It has been used to achieve late-stage incorporation of alkyl groups to a variety of biologically active heterocycles.
