We report an operationally convenient room temperature hydroboration of aldehydes and ketones employing Fe(acac) as precatalyst. The hydroboration of aldehydes and ketones proceeded efficiently at room temperature to yield, after work up, 1° and 2° alcohols; chemoselective hydroboration of aldehydes over ketones is attained under these conditions. We propose a σ-bond metathesis mechanism in which an Fe-H intermediate is postulated to be a key reactive species.

“…One of the challenges for the future generations of chemists and environmental experts is to evolve catalytic processes that integrate environmental objectives into global industrialization (1). Most catalytic processes are commanded by the use of noble, transition, or rare-earth metals, acting as active sites (2)(3)(4). Among various catalytic processes, O 2 activation is at the heart of many potential applications, most importantly in fine chemical synthesis, and environmental remediation (5,6).…”

Oxygen activation is a critical step in ubiquitous heterogeneous oxidative processes, most prominently in catalysis, electrolysis, and pharmaceutical applications. We present here our findings on metal-free O2 activation on covalent triazine frameworks (CTFs) as an important class of N-rich materials. The O2 activation process was studied for the formation of aldehydes, ketones and imines. A detailed mechanistic study of O2 activation and the role of nitrogen heteroatoms were comprehensively investigated. The electron paramagnetic resonance (EPR) and control experiments provide strong evidence for the reaction mechanism proving the applicability of the CTFs to activate oxygen into superoxide species. This report highlights the importance of a self-templating procedure to introduce N functionalities for the development of metal-free catalytic materials. The presented findings reveal an important step toward the use of CTFs as inexpensive and high-performance alternatives to metal-based materials not only for catalysis but also for biorelated applications dealing with O2 activation.

In order to produce a hydrogen stream for fuel cell utilization, the study of the ethanol steam reforming process over an alumina supported palladium commercial catalyst was carried out.The effect of the reaction temperature, the H,O/CzH60 molar ratios and the contact time on catalytic activity and stability was studied. It was [ound that even at very low temperature values complete ethanol conversion was possible. Hydrogen selectivities up to 98% were obtained at temperature values close to 625 ~ It was also observed that for different reactant molar ratios carbon monoxide concentration exhibits a minimum at a temperature value close to 450 ~ Furthermore, carbon formation was found to be negligible even for H~O/CzH60 molar ratios equal to the stoichiometric one.
