Abstract

4-Substituted 5-polycyclylpyrimidine compounds in which the 5-substituent is polycyclic and is attached to the pyrimidine moiety through an aliphatic carbon atom, such as 5-(2,2-dimethylindan-1-yl)-4-methylthiopyrimidine, were prepared and found to possess excellent herbicidal activity. The compounds are especially useful for the control of undesirable vegetation in paddy rice.
