4278-43-7 Usage
Description
ZINC TERT-BUTOXIDE, also known as zinc tert-butoxide, is a chemical compound derived from zinc and tert-butoxide. It is utilized in various chemical reactions and processes due to its unique properties and reactivity.
Uses
Used in Chemical Synthesis:
ZINC TERT-BUTOXIDE is used as a precursor in the chemical synthesis of ZnS (zinc sulfide) through a sol-gel process at room temperature. This process involves the use of zinc tert-butoxide and H2S in a toluene solution, allowing for the formation of ZnS.
Used in Catalytic Reactions:
ZINC TERT-BUTOXIDE is used as a catalyst in zinc-mediated epoxidation reactions. The equilibrium between zinc peroxide (R)-15 and zinc tert-butoxide (R)-16 in the presence of t-BuOOH is a key step in these reactions. ZINC TERT-BUTOXIDE's poor reactivity towards the iridium-bound cationic intermediate makes it an effective mediator in the deprotonation process, enabling the dual catalytic cycles to proceed feasibly.
Check Digit Verification of cas no
The CAS Registry Mumber 4278-43-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,7 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4278-43:
(6*4)+(5*2)+(4*7)+(3*8)+(2*4)+(1*3)=97
97 % 10 = 7
So 4278-43-7 is a valid CAS Registry Number.

A Zinc Catalyzed C(sp3)?C(sp2) Suzuki–Miyaura Cross-Coupling Reaction Mediated by Aryl-Zincates

The Suzuki–Miyaura (SM) reaction is one of the most important methods for C?C bond formation in chemical synthesis. In this communication, we show for the first time that the low toxicity, inexpensive element zinc is able to catalyze SM reactions. The cross-coupling of benzyl bromides with aryl borates is catalyzed by ZnBr2, in a process that is free from added ligand, and is compatible with a range of functionalized benzyl bromides and arylboronic acid pinacol esters. Initial mechanistic investigations indicate that the selective in situ formation of triaryl zincates is crucial to promote selective cross-coupling reactivity, which is facilitated by employing an arylborate of optimal nucleophilicity.
