We synthesized a series of acylphosphines and investigated the hydrosilylation of alkenes that were catalyzed using RhCl3/acylphosphine. The results indicated that RhCl3/(diphenylphosphino) (phenyl)methanone exhibited higher activity as well as higher levels of β–adduct selectivity.

A new route to phosphines was developed by a method that features a "pre-join and transform" process that proceeds via acylphosphine intermediates that may be readily prepared from carboxylic acids and disubstituted phosphines. The efficient decarbonylations of these acylphosphines using a nickel catalyst delivered the corresponding phosphines. This method shows that the carboxyl group can play a role similar to halides or triflates for introducing a substituted phosphorus atom on an aromatic ring.

Palladium-catalyzed C–P(III) bond formation reaction employing acylphosphines as the phosphorus source was developed. Under the optimized conditions, acylphosphines could react with aryl halides directly affording trivalent phosphines in up to 94% yield.

Enantioselective reduction of acylphosphines, after precomplexation with borane, proceeded smoothly in the presence of a chiral oxazaborolidine catalyst and catecholborane. α-Hydroxyalkylphosphine products were obtained as phosphine-borane complexes in good yield and enantioselectivity. One of the products of the enantioselective reduction was successfully applied as an optically active phosphine ligand for asymmetric catalysis after suitable derivatization.

The air sensitive aroyl- and acyldiphenylphosphanes RC(O)-PPh2 (2a - i) are obtained by reaction of the acyl chlorides RC(O)Cl (1a - i) with (CH3)3Si-PPh2 in petroleum ether.On access of water 2a - i are hydrolysed immediately.Starting from η5-C5H5Mn(CO)2THF (3x), BrMn(CO)5 (3y) and 2c - f the stable complexes LnMn-PPh2-C(O)R (4cx,dx,ey,fx) are formed. 1b - d, f - i can be transformed into the phosphane oxides RC(O)-P(O)Ph2 (5b - d, f - i) by Arbusov reaction with Ph2POCH3.From the oxides 5b - d, f and water, by a one pot reaction of 2b - d, f with HP(O)Ph2 andoxygen, or by the action of HP(O)Ph2 on 5a, f, the phosphinates -CHR (6a - d, f) are formed. 6a is produced also in form of the picolinium chloride 6a'.The electronic influences of the different aroyl residues on the reactivity of the aroylphosphanes 2c, d, f are investigated on the basis of the electronic and i.r. spectra of 4cx, dx, fx.The unusual stability of the methoxy compound 5f can be traced back to the strong +M effect of the 4-methoxybenzoyl residue.
