The invention relates to a method for synthesizing bis-oxoacetate compounds. The synthesis process is to form a reaction system with diamines, alcohol solvents, and oxalic acid diesters, and undergo nucleophilic substitution reactions to generate bis-oxoacetates containing The compound, the bis-oxoacetate compound is removed through refining, and the alcohol solvent is recovered and recycled to directly participate in the next reaction process. The invention improves the synthetic formula, so that the reaction system is carried out in an environment-friendly and easy-to-industrialized solvent; the alcohol solvent is easy to recover, can be recycled for many times, does not need additional solvents, and does not produce additional by-products, reducing production costs Reduce; do not use more dangerous solvents such as tetrahydrofuran, and the reaction yield is more than 90%. The alcohol solvent is easy to recover, can be recycled for many times, does not need to add additional solvents, does not produce additional by-products, and reduces production costs; no dangerous solvents such as tetrahydrofuran are used, and the reaction yield is over 90%. |
