Abstract
NEW MATERIAL:3-Iodopropargyl piperonyl ether of formula I-1, and 2,3,3-triiodoallyl piperonyl ether of formula I-2.
USE: A fungicide and preservative. Effective to prevent the degradation of industrial raw materials such as wood material, wet pulp, paper, etc. caused by fungi (fungi belonging to Penicillium genus, Aspergillus genus, etc. or wood discoloration fungi). Wood preservative for wood destroying fungi, white rot fungi, etc. Used in combination with a carrier (e.g. clay, talc) or an adjuvant (e.g. a cationic surface active agent) to promote the preservative and fungicidal activities.
PROCESS: The compound of formula VI is prepared by heating a compound of formula II and a compound of formula III (X is halogen), or a compound of formula IV and a compound of formula V, in the presence of a base. Reaction of the compound of formula VI with iodine in the presence of a base affords the titled compounds of formulas I-1 and I-2.
