Efficient synthetic methodology for preparation of 2-phosphiniminium-5- methylbenzenesulfonate zwitterions is reported. Staudinger reaction between phosphines and n-propyl 2-azido-5-methylbenzenesulfonates followed by sulfonate ester deprotection using pyridinium tetrafluoroborate/pyridine afforded the zwitterions in excellent yields. This new route directly accesses ortho-substituted-arenesulfonate ligands that incorporate a phosphinimine, a strong sigma-donor.

Cancer is one of the leading causes of deaths worldwide, due to the lack of effective anticancer agents, and the agents leading to side-effects. It is therefore crucial to find an anticancer agent which is effective enough to destroy the cancer cells without causing side-effects. Silver(I) complexes have the potential to be applied as effective anticancer agents, due to their excellent antibacterial and antimicrobial properties. Silver(I) benzyldiphenylphosphine complexes were synthesised and characterised by means of NMR, FTIR as well as single crystal X-ray diffractometry (SXRD). The crystal structure revealed a trigonal planar geometry, which is rarely seen in silver chemistry. In addition, the anticancer activity of these complexes was evaluated against a malignant SNO (oesophageal) cancer cell line. The viability of the cells after treatment with the complexes were determined using an alamarBlue viability assay. The possible mode of cell death, being apoptosis, necrosis or both, was determined by studying the treated cells under a microscope. A significant decrease in the viability of the cells after 24 h treatment with the complexes was observed. The morphological studies revealed that apoptosis could be a possible mode of cell death, however some necrosis was observed. Silver(I) benzyldiphenylphosphine complexes shows potential as effective anticancer agents.

The reductive cleavage of phenylalkylphosphines Ph2PR, PhPR2 (R = Bu, iPr) with Na/NH3 is unselective; both phenyl and alkyl groups can be cleavaged and Birch reduction may occur.Reaction of Ph2tBuP gives a high yield of diphenylphosphide.Polar groups (CO2Na, SO3Na) at the omega position of primary alkyl groups may lead to an increase in selectivity; Birch reduction is suppressed and a functionalised secondary phosphide is obtained.From diarylbenzyl- and diarylallylphosphines, the benzyl and allyl groups are selectively removed; Ar2PH and ArRPH are formed in high yield after hydrolytic work-up unless the aryl group bears F, CF3 or (CH3)2N substituents.From the reaction mixture of Ph2PCH2Ph we have isolated 1,2-diphenylethane. 2-Methoxyphenyl and 2,6-dimethoxyphenyl groups are selectively removed from Ar2BuP, ArPhBuP and Ar2P(CH2)3PAr2, forming ArBuPH, PhBuPH and ArP(H)(CH2)3(H)PAr, respectively.A double-cleavage reaction of Ar2RP may occur in low yield. 2,6-(dimethoxyphenyl-dibutylphosphine gives dibutylphosphine in moderate yield.When compounds with a 2,6-dimethoxyphenyl moiety are allowed to react with Li/THF, removal of a methyl group leads to novel phosphinophenols.It is concluded that cleavage of alkyl groups R selectively occurs when R radical is relatively stable (tBu, PhCH2> iPr > Bu).

Treatment of [IrCl3(tht)3] (tht = tetrahydrothiophene) with a stoichiometric amount of PPh3 gave the monosubstitution product [Ir(tht)2(PPh3)Cl3] (5), whose synthesis, particularly that leading to the effective preparation of OLED phosphors, was studied and optimized to achieve the best product yields. Thus, the independent treatment of 5 with 2,4-difluorophenylpyridine (dfppyH) or with variable amounts of benzyldiphenylphosphine (bdpH) gave rise to the formation of the cyclometalation products [Ir(dfppy)(tht)(PPh 3)Cl2] (7), [Ir(bdp)(bdpH)(tht)Cl2] (8), and [Ir(bdp)(PPh3)(tht)Cl2] (10), depending on the stoichiometry and conditions employed. Upon further treatment with 5-pyridyl-3-trifluoromethyl-1H-pyrazole (fppzH), these Ir(III) complexes 7, 8, and 10 were capable of yielding the phosphors [Ir(dfppy)(fppz)2] (1), [Ir(bdp)2(fppz)] (4), and [Ir(bdp)(fppz)2] (2), respectively. The general mechanism en route to their formation was studied and discussed.

Transesterification of phenylboronic and p-phenylenediboronic esters with phosphorus-containing polyols prepared by phosphine reactions with aldehydes leads to compounds containing two or more 1,3,2,5-dioxaboraphosphorinane rings linked together in various ways. The steric structure and reactivity of oligomeric 1,3,2,5-dioxaboraphosphorinanes are similar to those of mono- and di-1,3,2,5-dioxaboraphosphorinanes and controlled by np-sigma*C-O orbital coupling.

A series of benzyl(diphenylphosphino) and o-phenyl(diphenlyphosphino) substituted germylenes and plumbylenes were synthesized by nucleophilic substitution between the respective lithium reagent and tetrylene halide. The Lewis pairs were characterized by X-ray crystallography and NMR spectroscopy. The reactivity of the tetrylenes was investigated with respect to azide addition. In the germylene case, the germaniumimide was formed as the kinetically controlled product, which rearranges upon heating to give the phosphinimide. The stannylene and plumbylene derivatives react with adamantylazide to give the azide adducts. 1-Pentene reacts diastereoselectively with the phosphagermirane to give a cyclic addition product. Trimethysilylacetylene shows an addition with the benzylphosphino-substituted germylene and plumbylene to give the cycloheteropentene molecules. The addition product between phenylacetylene and the four membered Ge-P adduct shows after addition at room temperature a 1,4-phenylmigration to give a cyclic phosphine. Alkylnitrene insertion into a Ge?C bond of the alkyne addition product of the phosphagermirane was found in reaction with adamantylazide.
