Usage

Description

Cupric benzoate, with the chemical formula Cu(C6H5CO2)2, is a coordination complex derived from the cupric ion and the conjugate base of benzoic acid. It is known for its blue, crystalline powder form and is odorless. Cupric benzoate exhibits slight solubility in cold water, acids, and alcohol. One of its notable characteristics is that copper emits blue in a flame, making this salt a source of blue light in fireworks.

Uses

Used in Chemical Industry:
Cupric benzoate is used as a catalyst for the preparation of positive resist compositions, which comprise sulfonium compounds as acid diffusion inhibitors. This application is particularly relevant in the field of high-resolution and minimal line edge roughness, where precision and accuracy are crucial.
Used in Fireworks Industry:
Cupric benzoate is utilized as a source of blue light in fireworks due to the blue emission of copper in a flame. This property makes it a valuable component in creating visually stunning and colorful displays in the fireworks industry.

Preparation

In laboratory, copper benzoate can be made by combining aqueous solutions of potassium benzoate with copper sulfate. Copper benzoate precipitates as a pale blue solid : 2 C6H5COOK + CuSO4 →Cu(C6H5COO)2 + K2SO4 The primary use of this of this compound is in production of blue flame in fireworks. Copper benzoate made from sodium benzoate for use in fireworks may result in strong yellow dilution of the flame unless the precipitate is carefully washed to remove sodium ion (which emits brightly yello). Emission from potassium does not complicate the emission spectrum.

Purification Methods

Recrystallise it from hot water. Its solubility in EtOH/*C6H6 (90%) at 25o is 0.1%. [Crawford & Stewart J Chem Soc 228, 289 1953, Beilstein 9 H 84, 9 I 60, 9 III 376, 9 IV 280.]

Cu-Catalyzed C-H Alkenylation of Benzoic Acid and Acrylic Acid Derivatives with Vinyl Boronates

An efficient Cu-catalyzed C-H alkenylation with acyclic and cyclic vinyl boronates was realized for the first time under mild conditions. The scope of the vinyl borons and the compatibility with functional groups including heterocycles are superior than Pd-catalyzed C-H coupling with vinyl borons, providing a reliable access to multisubstituted alkenes and dienes. Subsequent hydrogenation of the product from the internal vinyl borons will lead to installation of secondary alkyls.

Copper(I) carboxylates of type [(nBu3P) mCuO2CR] (m = 1, 2, 3) - Synthesis, properties, and their use as CVD precursors

Copper(I) carboxylates of type [(nBu3P)mCuO 2CR] (m = 1: 3a, R = Me; 3b, R = CF3; 3c, R = Ph; 3d, R = CH=CHPh. m = 2: 4a, R = Me; 4b, R = CF3; 4c, R = Ph; 4d, R = CH= CHPh. m = 3: 8a, R = Me; 8b, R = CF3; 8c, R = CH2Ph; 8d, R = (CH 2OCH2)3H; 8e, R = cC 4H7O) are accessible by following synthesis methodologies: the reaction of [CuO2CR] (1a, R = Me; 1b, R = CF3; 1c, R = Ph; 1d, R = CH=CHPh) with m equivalents of nBu3P (2) (m = 1, 2, 3), or treatment of [(nBu3P)mCuCl] (5a, m = 1; 5b, m = 2) with [KO2CCF3] (6). A more straightforward synthesis method for 8a - 8e is the electrolysis of copper in presence of HO2CR (7a, R = Me; 7b, R = CF3; 7c, R = CH2Ph; 7d, R = (CH2OCH2)3H; 7e, R = cC 4H7O) and 2, respectively. This method allows to prepare the appropriate copper(I) carboxylate complexes in virtually quantitative yield, analytically pure form, and on an industrial scale. IR spectroscopic studies reveal that the carboxylic units in 4, 5, and 8 bind in a unidentate, chelating or μ-bridging fashion to copper(I) depending on m and R. The thermal properties of 4, 6, and 8 were determined by TG and DSC studies. Based on TG-MS experiments a conceivable mechanism for the thermally induced decomposition of these species is presented. Hot-wall Chemical Vapor Deposition experiments (CVD) with precursor 4b showed that copper could be deposited at 480°C onto a TiN-coated oxidized silicon substrate. The copper films were characterized by SEM and EDX studies. Pure layers were obtained with copper particles of size 200 - 780 nm.
