    Abstract: AN ARYL (HALOMETHYL) MERCURY COMPOUND OF THE FORMULA:

    R-HGC(H)N-1(X)4-N

    WHEREIN R IS SUBSTITUTED OR UNSUBSTITUTED ARYL, X IS HALOGEN AND N IS 1 OR 2 IS OBTAINED BY REACTING AN ARYL MERCURIC HALIDE, AN ALKALI METAL ALKOXIDE AND EITHER DIHALOMETHANE OR A TRIHALOMETHANE AT A TEMPERATURE BETWEEN -80*C. AND 0*C. THE REACTION IS CARRIED OUT IN A HIGHLY POLAR ETHEREAL SOLVENT FOR THE ARYL MERCURIC HALIDE REACTANT. THE ARYL (HALOMETHYL) MERCURY COMPOUNDS FORM DIHALOCARBENES IN SITU TO REACT WITH BASE-SENSITIVE OR WEAKLY NUCLEOPHILIC OLEFINS TO FORM THE RESPECTIVE GEM-DIHALOCYCLOPROPANES.

    Abstract: Silacyclopropanes having the following formula are provided:

    wherein R and R1 can be the same or different and can be hydrogen, alkyl, aryl, substituted alkyl or substituted aryl; n is an integer from 0 to 10; W, X, Y and Z can be hydrogen, alkyl, aryl, substituted alkyl, substituted aryl or W and X or Y and Z on the same ring constituent can be -(CH2)m- wherein m is an integer from 1 to 10. The silacyclopropanes are formed by reacting a bromolithiated compound of the formula:

    with a dihalosilane of the formula:

    wherein A and A1 are halo and debrominating the resulting product with zinc or magnesium in tetrahydrofuran.
