A series of triphenylphosphinecarboxamide (TPPc) derivatives were designed and synthesized as alternative reagents to triphenylphosphine for the facile reduction of azides. The TPPc derivatives performed as efficient reducing agents for the synthesis of primary amines without the need for an additional hydrolysis procedure. The TPPc derivatives were also applied to nucleic acid sensing using a RhAz-oligonucleotide conjugate in a DNA-templated fluorogenic reaction.

Direct asymmetric α-allylation of ketones with allylic alcohols is described. The combination of palladium with a new phosphine ligand bearing a chiral proline moiety promoted the reaction to afford the corresponding α-allylated ketones in moderate yield and enantioselectivity.

Addition of primary amines to N-[2-(diphenylphosphanyl)benzoyloxy] succinimide affords 2-diphenylphosphanylbenzamides, Ph2PC 6H4C(O)NHR (R = C(CH3)3, 3; R = H, 4; R = CH2CH2CH3, 5; R = CH(CH 3)2, 6). Addition of NiCl(η3-CH 2C6H5)(PMe3) to the deprotonated potassium salts of the amides and subsequent treatment of two equivalents of B(C6F5)3 to the resulting products furnishes η3-benzyl zwitterionic nickel(II) complexes, [Ph 2PC6H4C(O)NR-κ2N,P] Ni(η3-CH2C6H5) (R = C 6H5, 9; R = C(CH3)3,10; R = H, 11; R = CH2CH2CH3, 12; R = CH(CH3) 2, 13). Solid structures of 9, 11, 13 and the intermediate η1-benzyl nickel(II) complexes, [Ph2PC 6H4C(O)NR-κ2N,P]Ni(η1- CH2C6H5)(PMe3) (R = C 6H5, 7; R = C(CH3)3, 8) were determined by X-ray crystallography. When ethylene is added to the η3-benzyl zwitterionic nickel(II) complexes, butene is obtained by the complexes 9-12 but complex 13 provides very high molecular-weight branched polyethylene (Mw, ～1300000) with excellent activity (up to 5200 kg mol-1 h-1 at 100 psi gauge).
