Use of a compound of the formula: ##STR1## wherein X and Y are, same or different, each a lower alkyl group, a lower alkoxy group or a halogen atom and R is a methyl group or an ethyl group as a fungicidal agent against plantpathogenic fungi, particularly their drug-resistant strains.
Readily available phosphoramidites incorporating TADDOL-related diols with an acyclic backbone turned out to be excellent ligands for asymmetric gold catalysis, allowing a number of mechanistically different transformations to be performed with good to outstanding enantioselectivities. This includes [2 + 2] and [4 + 2] cycloadditions of ene-allenes, cycloisomerizations of enynes, hydroarylation reactions

protocol for the Pd(II)-catalyzed C-H alkenylation reaction of substituted N-allylanilines via an unusual 6-endo process has been developed. A density functional theory (DFT) study of the mechanistic pathway has shown that the coordination of the remote protecting group to the palladium center is determinant for the control of the regioselectivity in favor of the 6-endo process. The reaction would proceed

A fungicidal composition which comprises an N-phenylcarbamate of the formula
wherein X and Y are, same or different, each a lower alkyl group, a lower alkoxy group or a halogen atom and R is a methyl group or an ethyl group effective against phytopathogenic fungi, particularly their drug-resistant strains, is described. Those N-phenylcarbamates, where Y is a lower, alkyl group, a lower alkoxy group, a fluorine atom, a bromine atom or an iodine atom, are new compounds.
