Fluoroalkanesulfonyl bromides, RFSO2Br, RF = CF3, CF2CO2Et, CF2CF2OCH3, were used for addition of fluoroalkyl groups to the double bonds of allylcarboranes. These synthetic transformations were smoothly proceeded in good yields using the copper-catal

Globally, animal excreta (dung and urine) deposition onto grazed pastures represents more than half of anthropogenic nitrous oxide (N2O) emissions. To account for these emissions, New Zealand currently employs urine and dung emission factor (EF3) val

Condensation of amino groups in 5-(4-aminophenyl)-10,15,20-triphenylporphyrin and 5,10,15,20-tetrakis(4-aminophenyl)porphyrin with pentafluorobenzaldehyde resulted in corresponding Schiff bases and was shown to be a convenient route for the preparati

Diffusive Gradients in Thin-Films (DGT) have traditionally been used to measure time-weighted average concentration in water. We tested whether Br--DGT in combination with the trace-dilution flow rate method, could be used as a new approach for measu
