A method of production allocation for multiple wells, fields, or other individual production sources which feed a common collection tank or battery. For any or each of the individual production sources, an oil-soluble or water-soluble tracer solution is added to the product stream flowing from the source and one or more downstream samples are then taken prior to the point at which the product stream combines with the product streams from any of the other sources. The individual oil production rate or water production rate of the tested production source is then determined using (i) the concentration of the oil-soluble tracer or water-soluble tracer hi the tracer solution, (ii) the rate of addition of the tracer solution to the product stream, and (iii) the downstream concentration of the tracer in the oil phase or the water phase of the product stream.

coupling of a difluoroallylboronate with aryl and heteroaryl halides and triflates provides a convenient and broadly applicable synthesis of difluoroallylarenes. The difluoroallyl boron reagent is formed by a copper-catalyzed defluorinative borylation of the inexpensive reagent 3,3,3-trifluoropropene, and the products undergo a wide range of reactions to a series of difluoro-substituted analogs of common
