FLASH-THERMOLYSIS OF METHYLENEPHTALIDE AND 3-METHYLENE-2-COUMARANONE
Bloch, R.,Orvane, P.
, p. 3597 - 3600 (1981)
The synthesis and flash-thermolysis of methylenephtalide 1 and 3-methylene-2-coumaranone 2 are reported.At high temperatures ( 1000 deg C) these two isomeric lactones do not extrude CO2 but give rise to new clean thermal rearrangements.
