- Synthesis and properties of sterically congested cyclopentadienes and their transition metal complexes
-
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 to organometallic derivatives such as 2, (M=Mo or W) and Cp'2Fe.The spectroscopic and electrochemical properties of selected complexes have been investigated to probe the steric and electronic properties of the substituted cyclopentadienyl ligands.
