-
, (2016/10/10)
The invention relates to a synthetic method, in particular to a one-pot synthetic method for m-acetylbenzoic acid. According to the one-pot synthetic method for the m-acetylbenzoic acid, there is no need to purify an intermediate product. The reaction equation of the m-acetylbenzoic acid is shown in the description, wherein R refers to methyl or ethyl, and R1 refers to methyl or ethyl or n-propyl. Compared with synthetic methods in the prior art, the synthetic method has the advantages that raw materials are low in price and easy to get, reaction conditions are mild, the obtained intermediate product can be directly used for a reaction in a next step without being separated and purified, and therefore process cost is greatly lowered.

Carboxylation of short-lived organolithiums bearing electrophilic functional groups such as nitro, cyano, and alkoxycarbonyl groups with CO 2 to give carboxylic acids and active esters was accomplished in a flow microreactor system. The successful reactions indicate that gas/liquid mass transfer and the subsequent chemical reaction with CO2 are extremely fast. Carboxylation of short-lived organolithiums bearing electrophilic functional groups such as nitro, cyano, and alkoxycarbonyl groups with CO 2 to give carboxylic acids and active esters was accomplished in a flow microreactor system. The successful reactions indicate that gas/liquid mass transfer and the subsequent chemical reaction with CO2 are extremely fast (see scheme).

For the first time, we have successfully applied Co2(CO) 8 as an effective carbonyl source for the Pd catalysed alkoxycarbonylation of aryl halides affording the corresponding aryl esters under mild microwave conditions. A wide variety of esters and carbonyl derivatives were prepared using this protocol.
