    Abstract: The addition of a substituted 2-butene having the general formula

    EACH X independently, forming either the cis or trans isomer, is F, Cl, Br, I or H where not more than one X is H, each M independently is O or S, each Z independently is Cl or Br, EACH A independently is an inert substituent, such as F, I, methyl, phenyl, hydroxy, methoxy, nitro, carboxy, acetoxy, cyano, amino or sulfo, N AND M ARE INTEGERS OF 1 TO 5 PROVIDED THAT WHEN N M 1 EACH Z and X is Br and M O and provided that when one X is H then n and m are integers of 3 to 5, and i and j are integers of 0 to 2 where i
