Abstract
The use of CO2 as a C1 building block for chemical synthesis is receiving growing attention, due to the potential of this simple molecule as an abundant and cheap renewable feedstock. Among the possible reductants used in the literature to bring about CO2 reduction to C1 derivatives, hydroboranes have found various applications, in the presence of suitable homogenous catalysts. The current minireview article summarizes the main results obtained since 2016 in the synthetic design of main group, first and second row transition metals for use as catalysts for CO2 hydroboration.
Highlights
In recent years, the accumulation of greenhouse gases in the atmosphere has steadilyIn recent years, the accumulation of greenhouse gases in the atmosphere has steadily increased due to human activity [1]
The present review summarizes the main main results described described in the literature since 2016 on the synthetic aspects aspects of main group and transition metal-based homogeneous catalysts, and on the selectivity selectivity obtained obtained in in CO
With hydroboranes such as pinacolborane (HBpin) and 16a, (OCHO)Bpin was obtained in 68% yield and complete selectivity under the conditions described above in a 48 h run, whereas 16b gave the same product in 37% yield
Summary
The accumulation of greenhouse gases in the atmosphere has steadily. The combustion of fossil fuels for the production energy isofthe largest of greenhouse gas emissions. Carbon dioxide can be used to make added value products, by reactions such as copolymerization [4], hydrogenation [5,6], biochemical approaches [7], and electrochemical reduction [7,8]. Carbon dioxide can be used to make added value products, by reactions such as polymerization [4], hydrogenation [5,6], biochemical approaches [7], and electrochemical reduction [7,8]. There has been an increase in interest in the homogeneous reduction of CO2 using hydrogen [9,10,11], hydrosilanes [12,13,14,15] and hydroborates [16,17].
