In this work, two benzothioxanthene imide dyes demonstrate excellent photochemical properties. When used as photocatalysts, they work with amine and iodonium salt or sulfonium salt to form different three‐component systems for effectively initiating photopolymerization under visible light, through photoredox catalysis processes.

A straightforward synthesis of indazolo[3,2-a]isoquinolin-6-amines [PDF]
4-Substituted 1-bromoisoquinolin-3-amines were subjected to Suzuki coupling with o-nitrophenylboronic acid to yield 1-(2-nitrophenyl) isoquinolinamines, which participated in Cadogan cyclization with triethyl phosphite under microwave irradiation in a ...

Taxonomy of Chemical Bondings: Opportunities and Challenges
The recent focus on supramolecular and nanosized systems produced a major increase in the types of observed noncovalent interactions and in the diversity of terms used to designate them. A hierarchical categorization (taxonomy) of terms used to designate electrophile···nucleophile interactions is proposed here.

Benzyne-mediated rearrangement of 3-(2-pyridyl)-1,2,4-triazines into 10-(1H-1,2,3-triazol-1-yl)pyrido[1,2-a]indoles [PDF]
The reaction between 5-R-6-R1-3-(2-pyridyl)-1,2,4-triazines and benzyne generated in situ in toluene under reflux results in the formation of 10-(1H-1,2,3-triazol-1-yl)pyrido[1,2-a]indoles 3 in up to 60% yields instead of the expected 3-R-4-R1-1-(2 ...

Dopamine receptors (DR) ligands are potential drug candidates for treating neurological disorders including schizophrenia or Parkinson's disease. Three series of isoquinolines: (E)-1-styryl-1,2,3,4-tetrahydroisoquinolines (series 1), 7-phenyl-1,2,3,7,8,8a-hexahydrocyclopenta[ij]-IQs (HCPIQs) (series 2) and (E)-1-(prop-1-en-1-yl)-1,2,3,4 ...
