Abstract: Prepn. of aromatic urethanes (I) by catalytic reaction of an aromatic amine with a hydroxyl cpd., CO and an oxidising agent, either oxygen or a nitro cpd., is carried out at >=100 degrees C and >=50 bar in the presence of either (a) a noble metal and/or its oxide, sulphate, nitrate, halide and/or acetate as catalyst; or (b) catalytic amts. of Se and/or S contg. catalysts with additional basic cpds. as auxiliary catalysts. (I) are starting materials in prepn. of dyes, plant protecting agents, pharmaceuticals and polyurethanes. (I) can be used in prepn. of corresp. isocyanates and ureas (intermediates for above prods.). Process gives (I) in better yields, space-time yields and purity than previous processes which gave yields of e.g. 30%.

Abstract: Methacrylic acid and methyl methacrylate CH2 = C(CH3)-COOR' (where R1 is H or Me) are made by reacting propionic acid or methyl propionate CH3-CH2-COOR' with formaldehyde dimethylacetal CH3-O-CH2-O-CH3 (I) for 0.1-100 seconds. Reactions is in the presence of (i) 0-0.5 moles water per mol (I) and (ii) a catalyst comprising phosphates and/or silicates of Mg, Ca, Al, Zr, Th or Ti, opt. with the addn. of oxides of Zr, Al, Th and/or Ti and/or boric acid and/or urea. Catalyst is opt. modified by alkali(ne earth) carboxylates or cpds. forming these under the prevailing conditions, pref. with alkali propionate, KOH or LiOH. Process proceeds with high space-time yield and high selectivity to the prodn. of the desired prod. No additional diluent is required and the post treatment for recovery of the prod. is simple and economical in expenditure of energy. The unconverted (I) is easily recycled to the reaction.

Abstract: Tricyclic nitrogenous compounds having strong plant growth regulating properties are disclosed. The compounds display the general formula wherein A is one of several nitrogen-containing radicals, R1, R2, R3 and R4 are selected from various recited aliphatic, aryl, araliphatic and heterocyclic groups. R3 and R4 may also together form one of a number of nitrogen, sulfur and oxygen containing radicals. These compounds have a variety of uses, including the reduction of plant growth height without harm to the plant.
