Aldehydes and Ketones
... Step [1]: The nucleophile attacks the carbonyl group, cleaving the π bond and moving an electron pair onto oxygen. This forms a sp3 hybridized intermediate with a new C–Nu bond. Step [2]: protonation of the negatively charged O atom by H2O forms the addition product. ...

... for the Friedel-Crafts alkylation to work. In general, the NO2 should go on last if possible, because it is a deactivator and slows down the reactions. So, the molecule can be made by bromination and alkylation, in either order, along with removal the ortho isomer, which is the side product. At that ...

Copper perchlorate: Efficient acetylation catalyst
... achieved in contrast to some other catalysts. Acylal formation from aldehydes is found to be very rapid and at the same time keto groups remain unchanged. Thus the transition metal perclorates are better for acetylation hederoatoms and aldehydes than other metal perclorates and metal triflates. It m ...
