The synthesis of 1,3-dialkyl substituted cyclopentadienes, C5H4RR′, Cp′H (Va–g) (where R and R′ are tert-butyl, iso-propyl, neo-pentyl, cyclohexyl, or 1-methylcyclohexyl) is reported. These are synthesized by the nucleophilic addition of methyl or hydride anions to the corresponding 2-alkyl-6,6-dialkylfulvenes (IIIa–f) followed by hydrolysis. These substituted 1,3-cyclopentadienes have been converted
1,3-二烷基取代的环戊二烯,C 5 H 4 RR',Cp'H(Va–g)(其中R和R'为叔丁基,异丙基,新戊基,环己基或1-甲基环己基)。这些是通过将甲基或氢化物阴离子亲核加成到相应的2-烷基-6,6-二烷基富勒烯(IIIa–f)中,然后水解而合成的。这些取代的1,3-环戊二烯已转化为有机金属衍生物例如[CP'Fe(CO)2 ] 2,[CP'M(CO)3本人](MMo或W)和CP' 22Fe。为了研究取代的环戊二烯基配体的空间和电子性质,已经研究了所选配合物的光谱和电化学性质。
