An organocatalytic cascade vinylogous double 1,6-addition strategy for the synthesis of chiral chroman derivatives is reported. The cascade reaction follows oxa-Michael/1,6-addition reactions between orthohydroxyphenyl- ...

An efficient method to access 2-triazolyl thio-/selenopyridines with good to excellent yields by ruthenium(II)-catalyzed one-pot [3+2]/[2+2+2] cycloaddition reactions of azides, 1-alkynyl thio-/selenocyanates and 1,6-diynes ...

RuII-catalyzed intermolecular double [2+2+2] cycloadditions of 1,6-diynes and alkynylthiocyanates have been developed for the synthesis of 2-aryl thiopyridines. Aryl thiocyanates were isolated chemoselectively as a result ...

High-Speed Multi-Chip HTCC Packages for Avionics require careful considerations early in the design cycle to obtain the optimum electrical performance. Some design goals can be achieved with simple stackup or ...

Aryl cobaloximes, ArCo(dioxime)2Py (1e9) (Ar ¼ phenyl, 1-naphthyl, 2-naphthyl; dioxime ¼ dmgH, dpgH, gH) have been synthesized and characterized primarily by NMR and elemental analyses and molecular structures of four ...

Reactive oxygen species(ROS)are well known for their oxidizing behaviour but it differs in fluoresce in derivatives chemistry. With t-BuOOH,the probe F shows its unique turn-off sensing(A), while with NaOCl probe show ...
