| Abstract: | A Series of substituted cyclopentadienes, namely, C5H5RR'Ar,R = CH3, R' = CH3, C2H5, C3H2, CH2CH(CH3)2, R = R' =C2H5; R = R' = (CH2)5; Ar = C6H5, p-, m-, o-CH3C6H4 , .p-,o-CH3OC6H4 were prepared by the reaction of 6,6-dialkylfulvenes with aryllithium followed by treatment with water. For the steric effect of o-tolyl and o-methoxyphenyl, the chemical shifts of alkyl protons at 6-position in o-substituted phenyl cyclopentadienes split to two groups of signals. |
