A mono-tin organic compound for the synthesis of sucrose-6-carboxylate, wherein the mono-tin organic compound has a structure shown in formula (1):
- wherein R1, R2, and R3 each are independently selected from the group consisting of C1 to C8 linear or branched saturated alkyl, C2 to C8 linear or branched unsaturated alkyl, C3 to C8 substituted or unsubstituted saturated cycloalkyl, C3 to C8 substituted or unsubstituted unsaturated cycloalkyl, and C6 to C12 aryl or substituted aryl;
- and
- R4 is selected from the group consisting of C1 to C6 linear or branched saturated alkyl and C6 to C12 aryl or substituted aryl.
A method for preparing a mono-tin organic compound, comprising the following steps:
- dissolution:
- dissolving trialkyltin oxide in an organic solvent to obtain an organic reaction solution;
- wherein the trialkyltin oxide is a compound shown in formula (2):
- wherein R1, R2, and R3 each are independently selected from the group consisting of C1 to C8 linear or branched saturated alkyl, C2 to C8 linear or branched unsaturated alkyl, C3 to C8 substituted or unsubstituted saturated cycloalkyl, C3 to C8 substituted or unsubstituted unsaturated cycloalkyl, and C6 to C12 aryl or substituted aryl, preferably n-butyl;
- and
- acylation:
- under preset conditions, adding an acylating agent to the organic reaction solution and holding for a preset time, such that the trialkyltin oxide and the acylating agent are subjected to acylation;
