Transition metal-catalyzed semi-hydrogenation of alkynes has become one of the most popular methods for alkene synthesis. Specifically, the noble metal Pd, Rh, and Ru-based heterogeneous catalysts have been widely studied and utilized in both academia and industry. But the supported noble metal catalysts are generally suffering from leaching or aggregation during harsh reaction conditions, which resulting low catalytic reactivity and stability. Herein, we reported the facile synthesis of nitrogen doped graphene encapsulated Pd catalyst and its application in the chemo-selective semi-hydrogenation of alkynes. The graphene layer served as “”bulletproof”” over the active Pd Nano metal species, which was confirmed by X-ray and TEM anal., enhanced the catalytic stability during the reaction conditions. The optimized prepared Pd@N/C catalyst showed excellent efficiency in semi-hydrogenation of phenylacetylene and other types of alkynes with un-functionalized or functionalized substituents, including the hydrogenation sensitive functional groups (NO2, ester, and halogen).

Com. available and inexpensive lithium tert-butoxide (tBuOLi) acts as a good precatalyst for the hydroboration of esters, lactones, and epoxides using pinacolborane as a borylation agent. Functional groups such as cyano-, nitro-, amino-, vinyl, and alkynyl are unaffected under the presented hydroboration process, representing high chemoselectivity. This transformation has also been effectively applied to the synthesis of key intermediates of Erlotinib and Cinacalcet. Preliminary investigations of the mechanism show that the hydroboration proceeds through the in situ formed BH3 species.

Xiu, Fu-Rong; Wang, Yixiao; Yu, Xuan; Li, Yifan; Lu, Yongwei; Zhou, Ke; He, Jiahuan; Song, Zhiqi; Gao, Xiang published the artcile< Novel safety treatment strategy of DEHP-rich flexible polyvinyl chloride waste through low-temperature critical aqueous ammonia treatment>, Application In Synthesis of 104-76-7, the main research area is easte flexible polyvinyl chloride critical aqueous ammonia plasticizer dechlorination; Dechlorination; Low-temperature critical aqueous ammonia; Plasticizer recovery; Waste flexible polyvinyl chloride.

Flexible polyvinyl chloride (f-PVC) contains high content of plasticizers and chlorine. Improper treatment of waste f-PVC can easily lead to resource wasting and bring environmental risks. In this work, a novel strategy for resource recycling and dechlorination of waste f-PVC containing high content of di-(2-ethylhexyl) phthalate (DEHP) was developed by using low-temperature critical aqueous ammonia (LCA) process. The LCA treatment of waste DEHP-rich f-PVC (WDP) was performed at the temperature range of 200-400°C with the ammonia concentration of 1%-5%. The results indicated that the LCA temperature had a significant effect on the chem. composition of decomposition products. High concentration of 2-ethyl-1-hexanol (86.12%), which is an important chem. feedstock and is derived from the decomposition of DEHP, could be obtained from WDP by the LCA process at 250°C, and the concentration of 2-ethyl-1-hexanol decreased markedly with increasing the temperature Benzaldehyde and acetophenone were generated when the temperature increased to 300°C, and their concentrations increased with the rise of temperature The increase of the ammonia concentration and the temperature could enhance the dechlorination efficiency of WDP. The dechlorination could reach 98.7% at 300°C. This result showed that the LCA process was a promising and high-efficiency strategy for the sustainable management of WDP.
