Abstract: Methods of forming arenes, including asymmetrical arenes, such as asymmetrical pyrene derivatives. Substituents of starting materials may be selected to direct a photochemical cascade and possibly a 1,2-aryl shift. The methods may include a Mallory cyclization, which is controlled, at least in part, by substituents of the starting materials. Compounds and compositions including asymmetrical arenes.

Abstract: The activation of the C—H bond using low temperature plasma with an inlet liquid stream such that value added products are formed effectively. An organic liquid (e.g., hexane which is immiscible with liquid water) is injected into a flowing gas (argon) stream followed by mixing with a liquid water stream. Thereafter, the mixture contacts a plasma region formed by a pulsed electric discharge. The plasma formed with the flowing liquid and gas between the two electrodes causes chemical reactions that generate various compounds.

Abstract: A novel Rh(I)-catalyzed approach to synthesizing functionalized (E,Z) dienal compounds has been developed via tandem transformation where a stereoselective hydrogen transfer follows a propargyl Claisen rearrangement. Z-Stereochemistry of the first double bond suggests the involvement of a six-membered cyclic intermediate whereas the E-stereochemistry of the second double bond stems from the subsequent protodemetallation step giving an (E,Z)-dienal. The reaction may be represented by the following sequence.

Abstract translation: 提供了无机纳米晶体的光介导相转移的方法，例如发光量子点，量子点。 辐射，特别是紫外线激发（λex<400nm）促进疏水性量子点与亲水配体的原位配位体交换，并且它们容易转移到极性溶剂和缓冲介质中。 该技术使量子点和其他纳米晶体材料从疏水转移到极性和亲水溶液。
