State‐of‐the‐Art and Synthetic Challenges for Hydrosilane Production
Chemistry – A European Journal, EarlyView.The synthesis of hydrosilanes is currently energy intensive and their recycling is not considered. However, these compounds are important in many industrial fields but also for the valorization of oxygenated waste, towards a circular economy. This review compares the available synthetic routes and highlights the remaining challenges for the production ...

The mechanism of pyridine hydrogenolysis on molybdenum-containing catalysts : II. Hydrogenation of pyridine to piperidine [PDF]
, 1973 The kinetics of pyridine hydrogenation was studied at high hydrogen pressures on a Mo-Al oxide and a Co-Mo-Al oxide catalyst. The rate equation was found to be r = kPpyrPH2n/Ppyro, in which n is 1.5 at 300 and 375 °C and 1.0 at 250 °C. This rate equation

Polysilane‐Supported Nickel as an Efficient Catalyst for the Hydrogenation of Aromatic Compounds†
Chinese Journal of Chemistry, EarlyView.A Ni/Si catalyst obtained from the reaction of poly(monohydro)silane with Ni(cod)2 serves as an effective heterogeneous catalyst for the hydrogenation of arenes under reaction conditions that are significantly milder than those required for conventional nickel‐based catalysts such as Raney nickel.

Preparation of organic hydrazides [PDF]
, 1959 Thesis (M.A.)--Boston UniversityDue to the actual high price of hydrazine, this chemical cannot be used in an economical preparation of organic hydrazides. A synthesis of such hydrazides can be envisaged by the reduction of N-nitroamides.
