SPECIFIC HYDRATION AND NUCLEOPHILIC REACTIVITY OF ORGANIC ANIONS UNDER PHASE-TRANSFER CATALYSIS AND HOMOGENEOUS CONDITIONS
Landini, Dario,Maia, Angelamaria,Rampoldi, Alessandro
, p. 513 - 518 (2007/10/02)
The effect of specific hydration on the nucleophilic reactivity of the organic anions 3a-i has been studied under PhCl-aqueous NaOH (15-50percent) PTC conditions and in anhydrous chlorobenzene.The sensitivity to the specific solvation, in the order oxanion > carbanion >/= nitranion >/= thianion, can be explained on the basis of the different donor atom tendency.The data provide a useful guide to the choice of the best reaction conditions of these anions under PTC.
A FACILE AND CONVENIENT SYNTHESIS OF LIPOPHILIC TETRAALKYLAMMONIUM OR PHOSPHONIUM HYDROGEN SULFATES
Giorgi, Marco De,Landini, Dario,Maia, Angelamaria,Penso, Michele

Lipophilic tetraalkylammonium or phosphonium hydrogen sulfates are easily synthesized in very high yields by action of KHSO4 in 10percent aqueous sulfuric acid on the corresponding quaternary azides, the latter being obtained by preparative ion-pair extraction from quaternary methanesulfonates or chlorides.
