実験手順

The analysis of the crude reaction solution by gas chromatography revealed that the conversion of 1,1,1-trichloro-2-methyl-2-propanol was 70.0% and the yield of methyl 2-chloro-2-methylpropanoate was 23.9%. As to other products, it was obtained methyl methacrylate in a 0.7% yield, methacrylic acid in a 0.2% yield, (1,1,1-trichloro-2-methyl-2-propyl) methacrylate in a 7.8% yield, and (1,1,1-trichloro-2-methyl-2-propyl) 2-chloro-2-methylpropanoate in a 12.9% yield.
