A stannous methanesulfonate solution for tin electroplating applications and a method of forming the same are disclosed. The solution has an elevated pH. The solution also has a sufficient tin concentration for electroplating applications.

Stannous methanesulfonate solution with adjusted pH

Provided herein are methods for the preparation of high purity stannous oxide comprising: (a) reacting a Sn salt with a Cdicarboxylic acid in the aqueous phase to form a suspension comprising a Sn-dicarboxylate complex; (b) washing the Sn-dicarboxylate complex with water to obtain a wash solution comprising a washed Sn-dicarboxylate complex essentially free of the anion of the Sn salt; and (c) reacting the washed Sn-dicarboxylate complex with a base to form high purity SnO, wherein the high purity SnO has an alpha radiation count of less than about 0.002 cph/cm.

Method for the preparation of high purity stannous oxide

Conductive polymers and a method of forming conductive polymers. More particularly, a method of forming head-to-tail coupled regioregular poly-(3-substituted) thiophenes having improved charge carrier mobility and current modulation. Also, monomers having two different halogen leaving groups and which form regioregular poly-(3-substituted) thiophenes more efficiently and economically than other processes. Polythiophene polymers, films and articles are also provided.

Halogenated thiophene monomer for the preparation of regioregular polythiophenes

Provided are methods of producing phosphitylated compounds, including 3'-O-phosphoramidites, comprising the step of reacting a hydroxyl-containing compound with a phosphitylating agent in the presence of a phosphitylation activator selected from the group consisting of: (1) acid-base complexes derived from an amine base of Formula II wherein R, R, R, R, and Rare independently hydrogen, C&#x2013;Calkyl, C&#x2013;Ccycloalkyl, C&#x2013;Caryl, C&#x2013;Caralkyl, C&#x2013;Cheteroalkyl, or C&#x2013;Cheteroaryl, and at least one of R, R, R, R, and Ris not hydrogen; (2) zwitterionic amine complexes; and (3) combinations of two or more thereof, to produce a phosphitylated compound. Further provided are methods for purifying phosphitylated compounds comprising the steps of providing a phosphitylated compound in a solution solvent, contacting said phosphitylated compound with a precipitation solvent, and precipitating said phosphitylated compound.

Methods of producing phosphitylated compounds

An improved process and catalyst system for the isomerization of halothiophenes. More particularly, an improved process for the isomerization of 2-halothiopehenes to 3-halothiophenes by reacting a 2-halothiophene with a catalyst and in the presence of a base. The addition of a base additive to the acidic zeolite catalyst allows the desired isomerization reaction to take place while suppressing side-reactions that result in the decomposition of thiophene rings. The catalyst lifetime is thus increased and the amount of catalyst needed for the reaction is reduced, lowering cost.

Process for isomerization of 2-halothiophene to 3-halothiophene

A method for the formation of 3-alkylthiophenes or 3-arylthiophenes from 3-halothiophenes. More particularly, improvements on the Kumada coupling reaction for the production of 3-alkylthiophenes or 3-arylthiophenes by reacting a 3-halothiophene with an alkylmagnesiumhalide or arylmagnesiumhalide Grignard reagent in the presence of a catalyst and a 2-methyl tetrahydrofuran solvent. The 2-methyl tetrahydrofuran solvent allows for higher concentrations of the Grignard reagent with minimal or no dithienyl side product generation, achieving higher product yields and at a lower cost than other known methods.

Process for the Kumada coupling reaction

A process for producing a phenothiazinium compound comprising the step of: reacting phenothiazine, in the presence of a halogen, with at least one amine selected from the group consisting of: wherein Z is CH, O, S, SO, NH, NCH, NCH, NCHCHOH or NCOCH, and Rand Rare each independently linear or branched CHY.

Method for producing phenothiazinium compounds

Provided are methods of producing phosphitylated compounds, including 3'-O-phosphoramidites, comprising the step of reacting a hydroxyl-containing compound with a phosphitylating agent in the presence of a phosphitylation activator selected from the group consisting of: (1) acid-base complexes derived from an amine base of Formula Iwherein R, R, and Rare independently C-Calkyl, C-Ccycloalkyl, C-Caryl, C-Caralkyl, C-Cheteroalkyl, or C-Cheteroaryl, wherein any two adjacent R, R, and Rmay be connected to form a heterocyclic ring; (2) acid-base complexes derived from a diazabicyclo amine base; and (3) combinations of two or more thereof.
