Examples of solvent attack
WebIn the second step of an electrophilic addition, the positively charge on the intermediate combines with an electron-rich species to form the second covalent bond. The second step is the same nucleophilic attack process found in an S N 1 reaction. The exact nature of the electrophile and the nature of the positively charged intermediate are not ... WebFirst, NaBH4 is not so reactive and the reaction is usually carried out in protic solvents such as ethanol or methanol. The solvent has two functions here: 1) It serves as the source of a proton (H +) once the reduction is …
