WebA higher M n often improves device performance. 61 In that respect, we note that the two polymers with chlorinated side chains (J71–Cl and J101) have somewhat lower M n than the other two (J71 and J100) but still give rise to higher PCEs. This supports our conclusion that chlorination of the side chains causes the beneficial effect. WebPreparation of aldehydes from aromatic hydrocarbons. Aromatic aldehyde are prepared from aromatic hydrocarbons by the following methods: By oxidation of methylbenzene. By side chain chlorination followed by hydrolysis. By Gatterman Koch reaction.
WebPhotochemical reactions, such as the light-driven side-chain chlorination of various aromatic compounds, are among the cornerstones of the chemical industry. Therefore, reoptimising reaction conditions using state-of-the-art reactor designs and irradiation techniques is economically and ecologically of uttermost importance. WebWhat we claim is: 1. A method of chlorinating alkyl side chains of nitrogen heterocycles consisting essentially of reacting an α-alkyl side chain quasi aromatic nitrogen heterocycle in an inert solvent with trichloroisocyanuric acid at 20° to 200° C. whereby the side chain carbon atom attached to the nitrogen heterocycle is chlorinated. 2.
