Ph3SnCl
All reactions were carried out using P4 (0.025 mmol, 1 equiv.), Ar-I (1.1 mmol,
11 equiv. based on phosphorus atom), 3DPAFIPN (1.2 mol% based on
phosphorus atom) and Et3N (1.4 mmol, 14.4 equiv. based on phosphorus atom)
in CH3CN/PhH (3:1 v/v, 2 mL) under an N2 atmosphere and blue LED irradiation
(max = 455 nm) for 24 h. Yields were determined by quantitative 31P{1H} NMR
analysis of the reaction mixture with PPh3O as an internal standard. (a) 30 h
reaction time. (b) Values in parentheses are isolated yields for reactions at 1
mmol scale. (c) Ar-I was replaced by Ph3SnCl.

Conclusion
[2]
[3]
In summary, we have developed a mild and versatile, visible light-
mediated approach for the selective formation of a broad scope
of unsymmetrical aryl/aryl and aryl/alkyl tertiary phosphines and
quaternary phosphonium salts, using stable, commercially
available organic halides in combination with phenyl-substituted
primary and secondary phosphines as starting materials
(Scheme 3). Optimal results are obtained using low loadings of
an inexpensive organic photocatalyst, resulting in a mild and
versatile synthetic method for the preparation of these valuable
compounds and providing an attractive alternative to previously
developed Ir-photocatalyzed protocols. The same organic
photocatalyst can also be used to replace the precious metal
photoredox catalyst in our previously reported photocatalytic
arylation of P4, significantly improving the synthetic feasibility of
this important transformation.
