Triethyl-prop-2-ynyloxy-stannane, also known as (2-propynyloxy)triethylstannane, is an organotin compound with the chemical formula C?H??OSn. It is a colorless liquid that is sensitive to air and moisture. triethyl-prop-2-ynyloxy-stannane is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Stille coupling reaction, a type of cross-coupling reaction. In this reaction, triethyl-prop-2-ynyloxy-stannane acts as a nucleophile, facilitating the coupling of organic halides with alkenes or alkynes. Due to its reactivity, it is crucial to handle this chemical in an inert atmosphere, such as under nitrogen or argon, to prevent unwanted side reactions.
The CAS Registry Mumber 1067-60-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,6 and 7 respectively; the second part has 2 digits, 6 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1067-60: (6*1)+(5*0)+(4*6)+(3*7)+(2*6)+(1*0)=63 63 % 10 = 3 So 1067-60-3 is a valid CAS Registry Number.
