Question 4 1 pts Aldol and Claisen condensations are prone to "mixed products." Which of the following techniques can be used to help reduce the mixture of products one obtains in these reactions? O Make it so that one of the reagants does not have any "alpha protons." O Slowly add any reagants which you are concerned might readily self-react (react with themselves). O Heat the reaction up. OAll of the above. O 2 of the 3 above are correct.
Answer all please! Thank you in advance.
Many of the condensations we have studied are reversible. The reverse reactions are often given the prefix retro-, the Latin word meaning "backward." Propose mechanisms to account for the following reactions 22-76 CH H CH CH3 н* (b) (а) CH С- (сн), —сно CH ОН (retro-aldol and further condensation) но. (retro-aldol) CH OH (d) "ОСн, CH OН OH H,C-CH-CN СООCH (retro-Michael) (retro-aldol and crossed Claisen)

The Claisen-Schmidt type reaction is a variant of the aldol condensation and an example of an addition-elimination where carbon acids function as nucleophiles reacting with unsaturated carbon centered electrophiles. Consider the acid catalyzed reaction of the two reactants below. Describe the mechanism and products of such a reaction. (CH3)3C-C(=0)-CH2 + C6H5CH=0 Describe the mechanism and products in words please.
