AROMATIZATIONAL RHODIATION OF DENE-4-METHYL-4-TRICHLOROMETHYLCYCLOHEXA-2,5-DIENE UNDER THE ACTION OF (PH(3)P)(3)RH(CO)H AND (C2H4)(2)RH(ACAC) AS A NOVEL ROUTE TO P-TOLYLCYCLOPENTADIENYL COMPLEXES OF TRANSITION-METALS

Condensation of 4-methyl-4-trichloromethylcyclohexa-2,5-dienone with c
yclopentadiene gave the first representative of cross-conjugated penta
fulvenes of the paro-semiquinoid series: ene-4-methyl-4-trichloromethy
lcyclohexa-2,5-diene. This fulvene undergoes a novel redox aromatizati
onal skeletal rearrangement under the action of (Ph(3)P)(3)Rh(CO)H and
(C2H4)(2)Rh(acac) to give e[eta(5)-(p-tolylcyclopentadienyl)]dichloro
rhodium and -p-tolylcyclopentadienyl)(mu-chloro)chlorohodium], respect
ively.
