| titleOfInvention | Method for producing unsaturated carbonyl compound |
| abstract | (57) [Summary] [PROBLEMS] Formula (2) R 1 R 2 CHCR 3 (OCH 2 CR 4 = CR 5 R 6 ) 2 (2) (where R 1 , R 2 , R 3 and R 4 are A hydrogen atom, an alkyl group having 1 to 10 carbon atoms, an aralkyl group or an aryl group, wherein R 5 and R 6 are a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, an alkenyl group having 3 to 10 carbon atoms, R 1 and R 2 , or R 1 and R 3 may be taken together to represent an alkylene group having 1 to 10 carbon atoms.) High yield and simple formula (1) (Wherein R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are as defined above), which provides an industrially advantageous method for producing an unsaturated carbonyl compound represented by the formula: SOLUTION: Formula (3) Wherein R represents an alkyl group, an aralkyl group or an aryl group having 1 to 10 carbon atoms, and / or a salt comprising the phosphonic acid and a tertiary amine. The acetal represented by (2) is heated. |
