Abstract:
Transfer hydrogenation (TH) of six substrates catalyzed by Raney® nickel and conducted at 150 °C for 5 h under air or argon was studied. Significant decrease of conversion was observed under air as compared with TH under argon: 57% vs. 98% for menthone and 39% vs. 54% for camphor, respectively. Regardless of different reaction atmosphere used, aluminum segregated on the catalyst surface to form micron-sized alumina crystallites to modify the adsorption capacity, to inhibit the catalyst activity and to change the products selectivity of TH. Moreover, the changes of the catalyst structure under air entailed the change of reaction rates of both hydrodeoxygenation and dearomatization of acylbenzenes (ketones), as well as benzylic alcohols. Thus, manipulating by reaction atmosphere of TH catalyzed by Raney® nickel can be considered as an efficient tool to govern a chemo-, regio- and stereo-selectivity of products.
