 Title    Photochemical Reactions of 1-Hydroxy-1 H-benzotriazole and its Salts in Acetonitrile  
 Abstract    The photoreactions of 1-hydroxy-1H-benzotriazole and its salts are spectrophoto-metrically analyzed dependent on oxygen concentration in acetonitrile. Quantum yields have been determined.

 Title    3C NMR Spectroscopic Study of Pentacarbonylacetonitrilemetal(O) Complexes of the Group 6 B Elements  
 Abstract    The com plexes M (CO)5(C H 3C N) (M: Cr, M o, W) were obtained from the substitution o f TH F in M (C O)5(TH F) which has been generated by photolysis o f M(CO)6 in T H F and characterized by using IR , 'H N M R and l3C N M R spectrosco­ pies. The acetonitrile ligand is found to be N -bonded to the M (CO)5-moiety with a local C4v-symmetry. The effect o f the acetonitrile ligand on the metal-carbonyl bonding was discussed in terms o f l3C N M R chemical shifts.

 Title    Nitrogen-15 and Boron-11 NMR Spectroscopy of the System Acetonitrile / H-ZSM-5  
 Abstract    The interaction of adsorbed acetonitrile with microporous [Si,Al]-ZSM -5 and [Si,B]-ZSM-5 was investigated by solid state NMR. l:iN-CP MAS NM R of the system H-[Si,Al]-ZSM -5 / acetonitrile clearly shows the Bronsted and Lewis acid site interactions. Different coordina­ tion types of the complex ZSM-5/MeCN are considered. The accessibility o f the acid sites of [Si,B]-ZSM -5, a material structurally analogous to zeolite ZSM-5, was studied by " B-M AS NM R. The com plexation o f acetonitrile at the BO^ sites gives a narrow line at -4 ppm. In contrast to hydration phenomena of ZSM-5, the experiments show that acetonitrile is not capable of interacting with all of the BO 3 sites of the borosilicate, presumably due to steric effects.
