This invention relates to a method for retarding plant growth by applying to the plant an effective amount of a malonic acid derivative compound. This invention also relates to novel malonic acid derivative compounds and processes for the preparation thereof.
This invention relates to synergistic plant growth regulator compositions containing (1) an ethylene response or ethylene-type response inducing agent and (11) a malonic acid derivative compound. This invention also relates to the use of said compositions for inducing synergistic plant growth regulating responses or ethylene responses or ethylene-type responses.

been found to undergo a rhodium(II)-catalyzed transformation, producing five-membered ammonium or carbonyl ylides depending on the reaction conditions used. In the absence of an external dipolarophile, ammonium ylides are the exclusive products formed. In most cases these ylides cannot be isolated as they readily undergo sigmatropic rearrangement or fragmentation reactions. In the presence of typical
possible to trap some of the initially formed carbonyl ylide dipoles with a reactive dipolarophile such as DMAD. In other cases, cyclization of the dipole to the epoxide is much faster than bimolecular trapping. A related cyclization/rearrangement sequence occurred when diazo ketoamides derived from the cyclic pyrrolidone and piperidone ring systems were subjected to catalytic quantities of Rh(II) acetate
