METHOD FOR THE PRODUCTION OF CYANOACETIC ACID ESTERS |
摘要 |
The invention relates to a method wherein cyanoacetic acid -C1-4-alkyl esters are pyrolyzed to form 3,3'-bisisoxazol of formula (I) in the gas phase at reduced pressure in the presence of a C1-4-alkanol or by reaction of the pyrolysate with a C1-4-alkanol. Said cyanoacetic acid-C1-4-alkyl esters are used as intermediates in the synthesis of cyanoacrylates or pharmaceutically active agents. |
