In this paper, the effects of temperature and CO2 content on CO2 reduction (utilization) efficiency and physicochemical properties of pyrolysis/gasification biochar briquettes were investigated. The CO2 reduction (utilization) efficiency (CRE) reached the peak value of 74.9% in a 10% CO2/90% N2 atmosphere at 600 °C. The crackings of hydroxyl, CC bonds, methyl and methylene groups of biochars briquette...
The palladium(II)‐catalyzed hydroarylation of diphenylphosphorylallenes (via 1,2‐addition of the allenic double bond) with arylboronic acids in the presence of sodium hydroxide and oxygen is developed. The regioselectivities turn out to be well controlled, affording 2‐aryl‐3‐(diphenylphosphinyl)alkenes as the only product. Moreover, the stereoselectivities for reactions of γ‐substituted allenes can...
