Copper(I)t-Butoxide

[35342-67-7] C4H9CuO (MW 136.66) InChI = 1S/C4H9O.Cu/c1-4(2,3)5;/h1-3H3;/q-1;+1 InChIKey = WILFNLHOTDCRAO-UHFFFAOYSA-N (metalation agent for active hydrogen compounds;1 cross-coupling agent of 1,3-dinitrobenzenes and aryl iodides;2 nontransferable group of mixed organocuprates;3 volatile copper precursor for MOCVD4) Physical Data: sublimation temp 160 °C (0.1 mmHg), 110 °C (10−4 mmHg); mp 260 °C (dec). Solubility: slightly sol THF, benzene, cyclohexane, and hexane. Preparative Methods: CuI tert-butoxide prepared in situ by the metathesis reaction between Copper(I) Chloride and alkali metal tert-butoxide in appropriate organic solvents can be used for synthetic purposes. CuI tert-butoxide can be isolated by sublimation under vacuum. Handling, Storage, and Precautions: extremely oxygen- and moisture-sensitive. Preparation and reaction should be conducted under rigorously oxygen-free and anhydrous conditions.
