1-Chloro-borolane, also known as 1-chloro-5,5-dimethyl-1,3,2-dioxaborolane, is an organoborane compound with the chemical formula C4H9BO2Cl. It is a colorless liquid that is soluble in organic solvents and is widely used as a reagent in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. This reaction is a powerful method for the formation of carbon-carbon bonds, enabling the coupling of aryl or vinyl halides with arylboronic acids to form biaryls or alkenes. 1-Chloro-borolane plays a crucial role in this process by acting as a precursor to the boronate ester intermediate, which is then reacted with a palladium catalyst to facilitate the coupling. The compound is also known for its stability and ease of handling, making it a popular choice in various chemical transformations.
The CAS Registry Mumber 1692-29-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,9 and 2 respectively; the second part has 2 digits, 2 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1692-29: (6*1)+(5*6)+(4*9)+(3*2)+(2*2)+(1*9)=91 91 % 10 = 1 So 1692-29-1 is a valid CAS Registry Number.
