WebApr 12, 2024 · Other primary alkyl esters of phosphorous acid such as 2c–2e also took part in the phosphonylation yielding the corresponding phosphonates 3c–3e. As a comparison, secondary alkyl esters of phosphorous acid such as triisopropyl phosphite ( 2f ) gave a poor (∼3%) yield of the desired product 3f presumably because of steric hindrance. WebSN1 versus SN2. The nature of the nucleophile, the solvent, and the alkyl halide determine whether nucleophilic substitution takes place by the SN1 or the SN2 mecha-nism. With polar aprotic solvents, primary alkyl halides react faster than sec-ondary halides by the SN2 mechanism, whereas tertiary alkyl halides hardly react at all. http://www.chem.ucla.edu/harding/IGOC/P/primary_alkyl_halide.html chawla restaurant seattle
