Equilibrium acidities and homolytic bond dissociation enthalpies of the acidic C-H bonds in as-substituted triphenylarsonium and related cations

Equilibrium acidities (P.KHAS) of As-fluorenyltriphenylarsonium, As-phenacyltriphenylarsonium, six As-(panz-substituted benzyDtriphenylarsonium [p-GC6H4CH2+AsPh3] (G = H, Me, CF3, CO2Me, CN, and N02), and six P-(para-substituted benzyl)tri(ra-butyl)phosphonium [p-GC6H4CH2+P(w-Bu)3] (G = H, Me, CF3, CO2Me, CN, and NO2) bromide salts, together with the oxidation potentials [SOX(A-)] of their conjugate bases (ylides) have been determined in dimethyl sulfoxide (DMSO) solution. Introduction of an a-triphenylarsonium (a-PhsAs+) group was found to increase the adjacent C-H bond acidities by 13-20 pK units (18-27 kcal/mol). The equilibrium acidities for the two series p-GC6H4CH2+AsPh3 andp-GC6H4CH2+P(n-Bu)3 cations were found to be nicely correlated with the Hammett er constants of the correspondingpara-substituents (G) (Figures 1 and 2). The homolytic bond dissociation enthalpies (BDEs) of the acidic C-H bonds determined by using eq 1 reveal that an a-PhsAs"1" group increases the BDE value of the adjacent acidic C-H bond by 2-5 kcal/mol, whereas the substituent effects for an a-Ph3P+ or a-(w-Bu)3Pf group was found to be dependent on the nature of the substituents attached to the a-carbon atom. Good linear correlations were obtained for the equilibrium acidities of As-(para-substituted benzyDtriphenylarsonium and P-(parasubstituted benzyl)tri(?-butyl)phosphonium cations with the oxidation potentials of their conjugate bases (ylides) as shown in Figures 3 and 4, respectively.

Transylidation Reactions in Arsonium Ylides

Some substituted benzylidenetriphenylarsenanes have been generated from their precursors and treated with acid chlorides or acid anhydrides to afford intermediate arsonium salts which in the presence of starting ylides undergo transylidation to give carbonyl stabilized arsonium ylides in fair to good yields.The structures of these stabilized ylides were confirmed on the basis of their spectral data. - Keywords: Transylidation Reactions, Arsonium Ylides
