A convenient procedure has been developed for the preparation of Groupa 14 compounds by integrated palladium-catalyzed cross-coupling of aromatic iodides with the corresponding Groupa 14 hydrides in the presence of a base. The reaction conditions can be applied to the cross-coupling of tertiary, secondary, and primary Groupa 14 compounds. In most cases, the desired arylated products were obtained in synthetically useful yields. Even in the case of aryl iodides containing OH, NH2, CN, or CO2R groups, the reactions proceeded with good to high yields with tolerance of these reactive functional groups. A possible application of this method is the unique synthesis of a fungicidal diarylmethyl(1H-1,2,4-triazol-1-ylmethyl)silane derivative. A convenient procedure has been developed for the preparation of Groupa 14 compounds by integrated palladium-catalyzed cross-coupling of aromatic iodides with the corresponding Groupa 14 hydrides in the presence of a base (see picture). Application of this method in the synthesis of a fungicidal diarylmethyl(1H-1,2,4-triazol-1-yl-methyl)silane derivative is demonstrated. Copyright
