Benzamides were converted into benzonitriles with BrCCl 3 -PPh 3 -Et 3 N in CH 2 Cl 2 in an Appel-type reaction. Benzaldoximes could be transformed to benzonitriles under identical conditions. It was found that the reaction system BrCCl 3 -(2 equiv.)PPh 3 was also suitable for these transformations with PPh 3 replacing Et 3 N.

Two Ways of Preparing Benzonitriles Using BrCCl 3-PPh3 as the Reagent. -Both transformation can be carried out under the presented two conditions. General, 2-alkoxybenzamides and 2-alkoxybenzaldoximes give better yields in the presence of Et 3N. -(JASEM, Y. A.; BARKHAD, M.; KHAZALI, M. A.; BUTT, H. P.; EL-KHWASS, N. A.; ALAZANI, M.; HINDAWI, B.

Heat transfer fluids (HTFs) are used widely in many industrial processes. They collect and transport thermal energy in process heating, metal working, machine cooling with applications in the aerospace, automotive, and marine industries. Also, these fluids comprise one of the key technological components in electricity generation from concentrating solar power systems (CSPs), where they can store thermal energy as a sensible heat reservoir for later delivery to the power conversion system in absence of solar radiation. In the current work, a new one pot strategy towards biarylated ethers as novel Heat Transfer Fluids, while using minimal amount of reaction solvent, has been developed.
