, (2020/06/29)
Palladium-catalyzed C(sp3)–P(III) bond formation reaction for alkyl substituted phosphines preparation was developed. In this reaction, various alkyl bromides and limited alkyl chlorides reacted with acylphosphine under relative mild and easily accessible condition, and differential phosphines were afforded in good yields. This reaction made up the application of palladium catalysis in C(sp3)–P(III) bond formation, and indicated a practical application of acylphosphine as a phosphination reagent.
Radical alkylphosphanylation of olefins with stannylated or silylated phosphanes and alkyl iodides

scheme or table, p. 2236 - 2239 (2011/06/23)
Chemical equations presented. Intermolecular conjugate radical addition reactions of secondary and tertiary alkyl radicals derived from the corresponding alkyl iodides to activated olefins such as α,β- unsaturated esters, amides, imides, nitriles, and sulfones are described. The adduct radicals are trapped by either diphenyl(trimethylstannyl)phosphane or the commercially available diphenyl(trimethylsilyl)phosphane as chain transfer reagents to give the corresponding phosphanylated products in moderate to good yields. The overall process comprises a C-C followed by a C-P bond formation.
INFLUENCE OF MEDIUM ACIDITY ON THE INTERACTION OF TRIORGANYLPHOSPHINES WITH ALKYL HALIDES
Chauzov, V. A.,Guseva, N. N.,Kostina, L. P.
, p. 64 - 67 (2007/10/02)
The reaction rates of triphenylphosphine with amyl chloride, and of dioctylphenylphosphine with octyl chloride, are highest in protonated media having average acidity (pKa 10-13), and they decline sharply when transferred to media with higher o
