Will protocatechualdehyde condense with acetone or MEK? I couldn't find anything using the search engine or even google. Just information about other
aldehydes but nothing on protocatechualdehyde.
I know that the end compund depends on the catalyst used. What would be the products from condensing it with acetone or MEK, using either basic or
acidic catalyst?
I have around 50 grams of the above mentioned aldehyde and I don't want to experiment yet, because I don't really know what I can expect.

PHOTO-REIMER-TIEMANN REACTION OF
PHENOLS, ANILINES AND INDOLINE

Abstract
The photo-reaction of phenol (1) with chloroform in the presence of diethylamine gave salicylaldehyde (2) and 4-hydroxybenzaldehyde (3) in fair yield.
Dihydroxybenzenes, sensitive to alkali, under similar conditions without the base gave corresponding aldehydes and a cyclohexa-2.5dienone
(15). The photo-reaction was also applied to diethylaniline (18), indoline (21) and N-methylindoline (24). In carbon tetrachloride instead of
chloroform in an alcohol solution the same
type of reaction took place to give esters. The mechanism involving the coupling of a phenoxy radical or a radical cation with dichloromethyl radical
and not involving dichlorocarbene is proposed.

Piperonal is not what I am interested in. Even thou it smells nice.
