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 PMe_3-xPh_x, 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.
