An efficient Pd-catalysed β-C(sp3)-H arylation of diverse native amides with aryl iodides was developed. This protocol overcomes the necessity of the Thorpe-Ingold effect and features broad substrate scope and good functional group tolerance. The potential application of this protocol is collectively demonstrated by gram-scale synthesis and the synthesis of several bioactive molecules.

The invention relates to an improved process for the preparation of fungicidally active compounds of the formula STR1 wherein R1 and R2 individually are lower alkyl of from 1 to 4 carbons or halo-(lower alkyl) of from 1 to 4 carbons or R1 and R2 together with the carbon to which they are attached form a 3 to 7 membered cycloalkyl ring or lower alkyl-substituted cycloalkyl of from 4 to 9 carbons, R3, R4 and R5 individually are hydrogen or lower alkyl of from 1 to 4 carbons and X is methylene or oxygen, and salts of those compounds which are basic. The improved process comprises the reaction of a compound of the formula, STR2 wherein R3, R4, R5 and X have the significance given hereinabove, with a compound which forms a carbonium ion of the formula STR3 wherein R1 and R2 have the significance as given hereinabove.
