  • Catalytic scriabine reaction
    Patent number: 7524983
    Abstract: The present invention relates to the field of organic synthesis. More particularly it provides a process for making aromatic non-conjugated enol esters or enol ethers from an aromatic compound or moiety and a protected enal compound or moiety, such as an acetal or an acylal. The reaction is promoted by a salt of formula MX1-4, M representing a transition metal such as Zn or Fe and X representing a mono-anion, or by BY3, wherein Y represents a fluoride or a phenyl group optionally substituted.
    Type: Grant
