    摘要: DISCLOSED HEREIN ARE BICYCLOBUTANES OF THE FORMULA

    1-(R3-C(-R2)=C(-R1)-),2-R7,2-R6,4-R4,4-R5-BICYCLO(1.1.0)-

    BUTANE

    WHEREIN R1, R2, R3, R4, R5, R6, AND R7 MAY BE HYDROGEN OR A HYDROCARBYL GROUP OF 1-18 CARBON ATOMS WHICH IS FREE OF OLEFINIC OR ACETYLENIC UNSATURATION, WITH THE PROVISCO THAT THE PAIRS R1 AND R2, R2 AND R3, R4 AND R5, AND R6 AND R7 TAKEN TOGETHER MAY, RESPECTIVELY, BE TETRAMETHYLENE OR PENTAMETHYLENE DIRADICALS. THE ABOVE COMPOUNDS ARE PREPARED BY TREATING 3-ALKOXYCYCLOBUTANONE WITH A 1-ALKENYL GRIGNARD REAGENT TO OBTAIN THE CORRESPONDING 1-ALKENYL-3-ALKOXY-1-HYDROXYCLCLOBUTANE WHICH IS TREATED WITH A HYDROGEN HALIDE TO FORM A MIXTURE OF 1-ALKENYL-3-ALKOXY-1-HALOCYCLOBUTANE AND 3-ALKOXY-1-(2HALOALKENYLIDENE) CYCLOBUTANE. THOSE COMPOUNDS ARE THEN TREATED WITH A METAL CAPABLE OF REMOVING HALOGEN (SUCH AS SODIUM, MAGNESIUM, ZINC, ETC.) TO OBTAIN THE CORRESPONDING 1-(1-ALKENYL)BICYCLO(1.1.0)BUTANE. THESE BICYCLOBUTANES CAN BE CONVERTED TO HOMOPOLYMERS, WHICH ARE USEFUL AS SELF-SUPPORTING FILMS, FIBERS AND MOLDING POWDER.
