The use of Solid-Liquid Phase Transfer Catalysis without Solvent permits, by a careful selection of the reaction conditions, the selective preparation of the four products expected in the butylation of acetophenone.

Twist-twist π-conjugated (TTPC) π systems promise unique properties with their 90° twist angles. Di-sec-alkyl substituted stilbenes, 5, were prepared by low-valent titanium coupling of phenyl ketones, 4. Long alkyl chains stopped the coupling reaction. Stilbenes 5 were shown to be ～90% TTPC. Inserting TTPC units into poly(p-phenylene) polymers created highly fluorescent, soluble, TTPC π systems with weak electronic segmentation for organic light emitting diode (OLED) studies.

A π-π interaction in the transition state of the benzylation of 1,3-diphenyl-1-propanone, the monobenzylation product of acetophenone, is proposed according to chemical, kinetic and theoretical approaches. Evidence for the existence of this kind of interaction in a transition state has been provided for the first time. The results obtained cannot be explained solely by the increased acidity but by considering the existence of a π-π interaction.
