Abstract: THE INVENTION PROVIDES NEW DERIVATIVES OF 2,2-DIPHENYL3,3-DIMETHYLOXETANE IN WHICH THE PHENYL GROUPS ARE SUBSTITUTED WITH ALKOXY, ALKYLTHIO AND/OR METHYLENEDIOXY GROUPS. THE NEW COMPOUNDS HAVE INSECTICIDAL PROPERTIES AND THE INVENTION ALSO PROVIDES INSECTTICIDAL COMPOSITIONS THEREOF. THE COMOUNDS MAY BE MADE BY IRRADIATING A MIXTURE OF THE APPROPRIATELY SUBSTITUTED BENZOLPHENONE AND ISOBUTYLENE WITH ULTRA-VIOLET RADIATION.
