Experimental Outline In its simplest form, the aldol condensation is a self-addition involving two molecules of the same aldehyde or ketone, in the presence of a base, and results in the formation of a new carbon-carbon bond joining the carbonyl carbon of one molecule to the a-position of the second. In many cases - if the reaction conditions aren't sufficiently mild - the initially formed aldol product reacts further in an elimination reaction to give what is...

Rheosmin is a saturated ketone obtained from an
alpha,beta-unsaturated ketone (a crossed aldol condensation
product) which is capable of undergoing hydrogenation to yield a
saturated ketone (Rheosmin). Using this technique, identify the
reagents needed to prepare Rheosmin via crossed aldol reaction.
Rheosmin 4-(4-hydroxyphenyl)butan-2-one
