Synthesis, characterization, electrospinning and antibacterial studies on triphenylphosphine-dithiphosphonates Copper(I) and Silver(I) complexes

Background: The novel amido and O-ferrocenyldithiophosphonates [FcP(S)(SH)(NHR1)] (Fc = Fe(eta(5)-C5H5)(eta(5)-C5H4), R-1 = 1-(4-fluorophenylethyl and benzyloxycyclopentyl) and [FcP(S)(OR2)S-][H3N+C(CH3)(3)] (R-2 = myrtanyl) were synthesized by the reaction of [(FcPS(2))](2) (Fc = Fe(eta(5)-C5H5)(eta(5)-C5H4)) and chiral amines, such as (S)-(-)-1-(4-fluorophenylethyl) amine and (1S,2S)-(+)-benzyloxycyclopentyl amine, and of (1S), (2S), (5S)-myrtanol in toluene. The reaction of ferrocenyldithiophosphonates and [Cu(PPh3)(2)]NO3 or AgNO3 and PPh3 gave rise to copper(I) and silver(I) complexes in THF. [Ag-2{FcP(OMe)S-2}(2)(PPh3)(2)] and [Cu(PPh3)(2)]NO3 were embedded into nanofibers and their antimicrobial activities on fibers were also investigated.
