Example Sentences

By leveraging a light-sensitive borate intermediate, the scientists could transform quinoline derivatives into a great variety of 2D/3D fused frameworks in a straightforward and cost-effective manner.

From Science Daily

This process involves destabilizing one of the aromatic rings in quinoline, using light and sometimes a catalyst, so that a reactant can 'latch' onto the ring, forming the target compound.

From Science Daily

Despite many efforts, most studies have reported photocycloadditions happening on quinoline's benzene ring side, while few have targeted the pyridine side.

From Science Daily

The researchers discovered that this boron-containing compound was extremely effective at inducing dearomative photocycloaddition almost exclusively on the pyridine side of quinoline.

From Science Daily

Not only were the yields obtained high but also could a wide variety of quinoline derivatives and reactants be used to obtain all sorts of 2D/3D frameworks.
