Yield:101-43-9 93%
Reaction Conditions:
with C2H3O3(1-)*C37H78N(1+) in hexane at 90; for 2 h;Molecular sieve;
Steps:
64
General procedure: In Examples 62 to 64, as shown in Table 13, a transesterification reaction was carried out between methyl methacrylate which is an easily polymerizable ester compound and an alcohol compound. In Example 62, as in Example 24, lanthanum nitrate and tri n-octylphosphine were previously azeotropically refluxed with dimethyl carbonate for 1 hour, then dimethyl carbonate was evaporated at room temperature, The obtained catalyst was used. In Examples 63 and 64, methyltridodecylammonium methyl carbonate was used singly. As a result, ester products were obtained in high yield. It is to be noted that in Example 62, when using the isolated phosphonium salt as a catalyst instead of using the prepared catalyst as it is, it is predicted that the ester product is obtained with a higher yield than in Example 62 . Although not shown in Table 13, potassium tert-butoxide was used as a catalyst, and various by-products were produced.
