Title:
PRODUCTION OF 4-ALKOXY-1,1,1-TRIFLUORO-3-BUTEN-2-ONE
Document Type and Number:
Japanese Patent JP3843152
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a 4-alkoxy-1,1,1-trifluoro-3-buten-2-one useful as an active ingredient of an agrochemical, etc., by a short and simple reaction process in high yield.
SOLUTION: A halide of the formula, CF3COHal (Hal is a halogen atom) such as trifluoroacetyl chloride is reacted with a compound of the formula, CH2=CHOR (R is an alkyl) such as ethyl vinyl ether in the presence of a base such as pyridine to give a 4-alkoxy-1,1,1-trifluoro-3-buten-2-one of the formula, CF3CO-CH=CH-OR such as 4-ethoxy-1,1,1-trifluoro-3-buten-2-one.
