Rational Synthesis of Metallo-Cations Toward Redox- A nd Alkaline-Stable Metallo-Polyelectrolytes

Cations are crucial components in emerging functional polyelectrolytes for a myriad of applications. Rapid development in this area necessitates the exploration of new cations with advanced properties. Herein we describe a combination of computational and experimental design of cobaltocene metallo-cations that have distinct electronic and redox properties. One of the direct outcomes on the first synthesis of a complete set of cation derivatives is to discover highly stable cations, which are further integrated to construct metallo-polyelectrolytes as anion-exchange membranes in solid-state alkaline fuel cells. The device performance of these polyelectrolytes under highly basic and oxidative environments is competitive with many organo-polyelectrolytes.

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.

Improved Preparation of Polyisopropyl- and -tert-butylcyclopentadienes

Phase transfer catalytic isopropylation or tert-butylation of cyclopentadiene yields 1-6 in efficient one-pot procedures.Powdered potassium hydroxide or solid sodium hydride are the prefered bases, Aliquat 336 or dibenzo-18-crown-6 are the PT catalysts. +"--"+ Phase Transfer Catalysis, Potassium Hydroxide, Sodium Hydride

PHASE TRANSFER CATALYZED TERT-ALKYLATIONS OF CYCLOPENTADIENE AND INDENE: INDICATIONS FOR SET PROCESSES

Scope and mechanism of the PTC tert-alkylation of cyclopentadienide anion have been investigated.On the side of the anion, the reaction is limited to cyclopentadiene and indene, whereas many tertiary as well as secondary and primary alkylating agents can be employed.Hexamethylcyclopentadiene 8, for instance, is available easily.Tert-alkylations of this type are more effective if 4,4'-bipyridinium salts are present in addition to a phase transfer catalyst.The reactions involve probably an initial single electron transfer (SET) step.
