Acylpyridinium ions have been known as catalytically active species in acylation reactions catalyzed by 4-dimethylaminopyridine and its analogues. Acylpyridinium carboxylates were found to be 800-1300 times more reactive than the corresponding acylpyridin

Thallium(III) chloride is a simple and efficient catalyst for acylation of alcohols, phenols and thiols. It is also very effective for geminal diacylation of aldehydes. The acylation reaction using acetic anhydride proceeds in excellent yield in the presence of catalytic amounts of thallium(III) chloride (1 mol%) at room temperature within relatively short reaction times (20 min). Structurally diverse alcohols, phenols, thiols and aldehydes undergo acylation under solvent-free conditions.
Barriers to Internal Rotation in Neopentylbenzenes Substituted on the Benzyl Group. A 13C NMR Band Shape Study
Andersson, Sven,Drakenberg, Torbjoern
, p. 730 - 744 (2007/10/02)
Two series of neopentylbenzenes with one or two substituents on the benzyl group have been synthesized.In one series the substituents were H, F, Cl, Br, I, OCH3, OCOCH3, OSi(CH3)3, CH3 and CH2CH3, and in the other OH and R R = H, CH3, CH2CH3, (CH2)3CH3,
