An oxidativecoupling of amines to give imines in ionic liquids (ILs) under metal-free aerobic conditions has been developed. The high efficiency achievable in ILs is mechanistically explained in terms of activation of the starting materials (benzylamine and molecular oxygen) by an initial electron transfer, promoted by the ionic nature of the solvent. Reactivity data of variously p-substituted benzylamines

Compositions and methods for regulating plant growth are disclosed. The compositions comprise a compound of the formula
wherein R is selected from the group consisting of phenyl, phenylethenyl and alkyl having one to twelve carbons and R' is selected from the group consisting of phenyl and alkyl having one to twelve carbons in combination with an inert carrier. Dimers and salts of the above compounds are also disclosed. The compounds, preferably in an aqueous carrier, are applied to oil, fiber, root or grain crops in amounts ranging from 0.01 to 0.5 pounds of active ingredient per acre. Application may be effected by soil treatment either prior to or after planting or by treatment of the emergent plant. Application of the compositions generally results in increased plant height, plant weight and/or yield.

in order to provide a material having the properties of polyurethane foam and being adapted to change color with changes of temperature, a thermochromic polyurethane foam is obtained by reacting and foaming a mixture of a polyol and a polyisocyanate as main components, a thermochromic composition serving as a coloring agent being added to the main components singly or together with a usual dye or pigment, the thermochromic composition containing an electron-donating chromogenic material, an acidic substance and a solvent. The thermochromic composition may be enclosed in the form of microcapsules. The foam is used to provide manufactured articles with a temperature sensing and indicating function.
