Process for Preparing Aromatic Olefins |
摘要 |
Prodn. of mono-, di- or poly-functional aromatic olefins is effected by reacting haloaromatic cpds. with olefins at 20-220 degrees C in the presence of a Pd complex catalyst of formula: (LaPdbXc)<n>An (I) X = a charged or uncharged mono- or poly-dentate ligand co-ordinated to Pd; L = a carbene ligand of formulae (II)-(V) co-ordinated to Pd: R1-R6 = opt. sulphonated 1-7C alkyl, 5-18C alicyclic, 2-5C alkenyl, 6-14C aryl or 7-19C aralkyl gps.; or R3-R6 may also be H; or R3+R4 and R5+R6 = opt. sulphonated 3-7C divalent gps.; or R1, R2, R4 or R6 may form a ring with X; Y = a satd. or unsatd. 1-4C alkylidene gp. or a dialkylsilylene or tetraalkyldisilylene gp.; A = an anion; b = 1-3; a = 1 to 4b; c = 0 to 4b; n = 0-6. |
