Abstract: Light activated acyl-enzymes of the formula: ##STR1## are disclosed. In the compounds of Formula (III), ENZ is an enzyme, X is O or S, Y is --NR.sub.3 R.sub.4, --OR.sub.5, or --SR.sub.5, and Z is a nucleophile. m is 0 to 3 and n is 1 or 2. Y is substituted on the ring at either or both of the 4 and 6 position.R.sub.1 and R.sub.2 are each independently H, C1 to C4 alkyl, C3 to C4 unconjugated alkenyl, or C3 to C4 unconjugated alkynyl.R.sub.3 and R.sub.4 are each independently H, C1 to C4 alkyl, C3 to C4 unconjugated alkenyl, or C3 to C4 unconjugated alkynyl, except that R.sub.3 and R.sub.4 are not simultaneously both H. R.sub.5 is C1 to C4 alkyl, C3 to C4 unconjugated alkenyl, or C3 to C4 unconjugated alkynyl.Methods of using the acyl-enzymes and intermediates for making the acyl-enzymes are disclosed.

Abstract: N-alkylated anilines can be prepared by reaction of anilines with lower alcohols or dialkyl ethers at elevated temperature and in the presence of zeolite catalysts of the pentasil type containing protons and having an SiO.sub.2 /Al.sub.2 O.sub.3 ratio of at least 60.

Abstract: A process for the reduction of nitrobenzene is described. The reaction is performed catalytically in an aqueous acid medium in the presence of a small amount of organic acid, such as a lower carboxylic acid, oxalic acid, methanesulfonic acid or trichloroacetic acid.
