Abstract
Ultra short acting neuromuscular blocking agents of Formula (I) which are useful as skeletal muscle relaxants during emergency intubation procedures, routine surgery and post-operative settings are disclosed, wherein q and t are independently from 0 to 4; X.sup.1 and X.sup.2 are independently halogen; h.sup.a and h.sup.b are independenity from 0 to 2; Z.sup.1 and Z.sup.2 are indepentdently hydrogen, C.sub.1-6 alkyl, C.sub.2-6 alkenyl or C.sub.2-6 alkynyl with the proviso that Z.sup.1 and Z.sup.2 are not both hydrogen; Y.sup.1, Y.sup.2, and Y.sup.3 and Y.sup.4 are independently hydrogen, halogen or C.sub.1-3 alkoxy; m and p are independently 1 to 6; n and r are independently 0 to 4; with the proviso the if h.sup.a and h.sup.b are both 0, then r is 0 and n is 0 to 2; R.sup.1 to R.sup.14 are independently hydrogen, halogen, C.sub.1-3 alkoxy, or R.sup.2 and R.sup.3 together with the carbon atoms to which they are bonded, R.sup.5 and R.sup.6 together with the carbon atoms to which they are bonded, R.sup.9 and R.sup.10 together with the carbon atoms to which they are bonded, R.sup.12 and R.sup.13 together with the carbon atoms to which they are bonded, may independently form a methylened…
