Web0.196 mmol) in 5 mL of acetone was prepared. Addition of silver tetrafluoroborate (76.0 mg, 0.39 mmol) resulted in a yellow precipitate which was filtered off. A solution of the isopropenyl ligand (2) (218 mg, 0.389 mmol) was prepared in acetone and added dropwise to the yellow acetone solution of the rhodium cation, resulting in an orange-red ... Web2. Solvent Effects. Solvation of nucleophilic anions markedly influences their reactivity. The nucleophilicities cited above were obtained from reactions in methanol solution. Polar, protic solvents such as water and alcohols solvate anions by hydrogen bonding interactions, as shown in the diagram on the right.
WebThe general guideline for solvents regarding the nucleophilic substitution reaction is: S N 1 reactions are favored by polar protic solvents (H 2 O, ROH, etc.), and usually are … WebIn chemistry the solvents are qualitatively grouped into non-polar, polar aprotic, and polar protic solvents. A protic solvent is a solvent that has a hydrogen atom bound to oxygen (as in a hydroxyl group) or nitrogen (as in an amine group). In general terms, any solvent that contains a labile H+ is called a protic solvent.
