the reaction of benzaldehyde mth LiCH2CN in THF is controlled by carbonyl complexation while uith KCH2CN the reaction is controlled by ionic association. In the reaction of m.Cl.C6H4CHCN−Li+ with substituted benzaldehydes carbonyl complexation prevails with p.CH3OC6H4CHO while ionic association dominates uith PhCHO and p.CNC6H4CHO.
LiCH 2 CN在THF中的苯甲醛反应通过羰基络合控制,而KCH 2 CN则通过离子缔合控制反应。在m.Cl.C的反应6 ħ 4 CHCN -李+与取代的苯甲醛羰基络合盛行与p.CH 3 OC 6 H ^ 4 CHO而离子缔合占优势uith苯甲醛和p.CNC 6 ħ 4 CHO。
