Abstract:
A complex which is(A) a complex of formula(BISPHOS) M.fwdarw.L.sub.n,wherein n is an integer and is 0, 1, 2, 3 or 4;M is Rh, Ir, Ru or Pd;L is a ligand which is(a) norbornadiene;(b) C.sub.1-4 alkyl OH;(c) NR.sup.1 R.sup.2 R.sup.3, and R.sup.1 and R.sup.2 R.sup.3 are independently H, C.sub.1-4 alkyl, C.sub.3-7 cycloalkyl, aryl, pyridyl, or tetrahydrofuryl; or(d) a diene of the formula ##STR119## wherein m is an integer and is 1, 2, 3 or 4; n is an integer and is 0,1,2,3 or 4; and R.sup.4, R.sup.5, R.sup.6 and R.sup.7 are independently H or C.sub.1-4 alkyl;(e) ether of the formula R.sup.a OR.sup.b wherein R.sup.a and R.sup.b are independently C.sub.1-4 alkyl, C.sub.3-7 cycloalkyl, aryl, pyridyl, or tetrahydrofuryl;(f) cyclic ether of the formula ##STR120## wherein p is an integer and is 2, 3, 4 or 5; (g) bis-ether of the formula ##STR121## wherein m is defined as above; (h) bis-alcohol of the formulaHO--(CR.sup.8 R.sup.9).sub.p --OHwherein p is defined as above; and R.sup.8 and R.sup.9 are independently H, C.sub.1-4 alkyl or aryl; or(i) ethylene;BISPHOS is a compound of the formulae ##STR122## wherein R is C.sub.1-4 alkyl, C.sub.3-6 cycloalkyl, or aryl unsubstituted or substituted with --F, --CH.sub.3, --CF.sub.3 or CH.sub.3 O--; and X.sup.1 and X.sup.2 link the two R.sub.2 P-substituted benzenes and independently form a 2 to 4 membered link consisting of 2 to 4 carbon atoms;(B) a complex of structure ##STR123## wherein R is as defined above and R.sup.10 is CF.sub.3 or CH.sub.3 ; or (C) a complex of structure ##STR124## wherein R is as defined above.
