An efficient Rh(III)-catalyzed stepwise ortho allylation of N-methoxybenzamides 1 with polysubstituted allenes is reported. This C-H functionalization involving allenes is conducted under very mild conditions (-20 C or room temperature) and compatible with ambient air and moisture, and it can be applied to terminal or internal allenes with different synthetically attractive functional groups. Highly efficient axial chirality transfer has been realized, yielding optically active lactones.

A method of making a soluble thermoplastic polyimide composition, which comprises the steps of: polymerizing a first diamine, a second diamine different from the first diamine, and a dianhydride in a polar aprotic solvent to obtain a polyamine acid, wherein the first diamine contains a carboxyl group; and imidizing the polyamine acid to obtain the composition, wherein the composition contains the carboxyl group. By controlling the content of the dianhydride within a range from 85 mol. % to 99 mol. % based on the total content of the first diamine and the second diamine, the soluble thermoplastic polyimide composition made from the method can be laminated with a commercial polyimide film and a metal foil via simple steps of coating, drying, and pressing, to form a polyimide metal laminate. Therefore, by utilizing the soluble thermoplastic polyimide composition made from the method, making a polyimide metal laminate is simple and economical.

A simple and efficient method for the coupling of aryl iodides with heterocyclic compounds such as diazoles that does not require the use of alkoxide bases is described. The C-N bond forming procedure shows that the combination of air stable CuI and 1,10-phenanthroline in the presence of KF/Al2O3 comprises an extremely efficient and general catalyst system for the N-arylation of aryl iodides. Different functionalized aryl iodides were coupled with diazoles using this method. Georg Thieme Verlag Stuttgart.

Described herein is an asymmetric allylic aromatization (AAAr) strategy that employs readily accessible equivalents of benzylic nucleophiles in iridium-catalyzed allylic substitution reactions with the concomitant formation of aromatic rings by aromatization. The optimized reaction conditions involving a catalyst derived from a commercially available iridium precursor and the Carreira ligand are compatible with equivalents of benzylic nucleophiles derived from 4- or 5-methyloxazoles, 5-methylthiazoles, 4- or 5-methylfurans, 2- or 3-methylbenzofurans, 3-methylbenzothiophene, 3-methylindole, 1-methylnaphthalene, and methylbenzene. This strategy provides straightforward accesses to valuable heterocyclic aromatic compounds, bearing a homobenzylic stereogenic center, in an enantiopure form and would be difficult to access otherwise. The versatility of the reaction was showcased by the further elaboration of the products into useful building blocks and a drug analogue.
