Abstract

Various substituted phenyl, pyridyl and benzyl zinc chlorides have been generated from the corresponding lithium or magnesium organometallic reagents. These have been cross- coupled with 2-(6-bromo-2-pyridyl) pyrimidines in the presence of tetrakis (triphenylphosphine) palladium (0) to produce a series of substituted pyridylpyrimidine fungicides in 32–99% yields.
