ChEBI: 1,3-benzodioxole is a benzodioxole consisting of a benzene ring substituted by a the methylenedioxy group. Production Methods 1,3-Benzodioxole is a colorless liquid. This compound is prepared by the reaction of catechol and dihalomethanes, for example, by use of concentrated aqueous alkali...
The rotational spectrum of 1,3-benzodioxole has been investigated in the frequency range 30–40 GHz. Six vibrational satellites have been observed and assigned to excited states of the puckering and twisting modes of the five-membered ring moiety. On the basis of the observed zigzag behaviour of...
A mild and general method for the synthesis of potentially bioactive 2-substituted-1,3-benzodioxoles is presented. This is based on the photocatalyzed activation of methylene hydrogen atoms in the pre... Computer graphics analysis of the interaction of alkoxy methylenedioxybenzenes with cytochromes ...
