A dilute solution of bromine is added to samples of heptane and cyclohexene. The bromination reactions and mechanisms are compared. UV light splits the bromine molecule into two reactive radicals, ...

Since the 1970s, several C–C bond-forming reactions catalysed by transition-metal complexes have been developed that use mild (weakly acidic or basic) or neutral reaction conditions, to address the ...

Snow and ice influence the climate and chemistry of the polar atmosphere. Field experiments in Alaska point to the significance of surface snow for polar ozone depletion events. The connection between ...
