Abstract
UV photolysis has been used to generate dinitrogen compounds by substitution of CO groups by N2 in supercritical fluid solvents (scXe, scCO2 and scC2H6) containing high pressures of N2. Compounds include Cp'Mn(CO)2L (Cp′ C5H4Me; L PMe3-xPhx, x = 0 to 3). A semi-quantitative comparison of the photolysis of Cp{black star}Mn(CO)3 (Cp{black star} C5Me5) and N2 in ScXe and scCO2 indicates that there is little difference between the effectiveness of the photolysis in these two supercritical solvents. The Timney Ligand Effect approach is used to rationalise the fact that some of the ν(CO) and ν(NN) bands of Cp{black star}Mn(CO)2(N2) and Cp{black star}Mn(CO)(N2)2 are nearly coincident.
