摘要
羰基化合物特别是亚甲基化合物由于存在酮烯平衡，根据溶剂性质、共振和氢键的不同，通过烯醇和烯醇形成取代氧化、加成等类型的反应。在这些化合物中，- 2基团夹在两个吸引电子的> C = O基团之间，呈强酸性，烯醇化迅速，并通过共振稳定。
Kinetic Study of Some Active Methylene Compounds by Isoquinolinium Bromochromate
The carbonyl compounds especially methylenecompounds exhibit a substitution oxidation, addition etc. types of reactions through enol and enolate in formation because of existence of keto-enol equilibrium, depending on the nature of solvents, resonance and hydrogen bonding. In these compounds the –CH2group is sandwiched between two electron attracting > C = O groups, being highly acidic, enolize rapidly 1 and is stabilized by resonance.
