S-allyl S-methyl dithiocarbonate undergoes retro-ene type fragmentation, catalyzed by Lewis acids such as AlCl3 or Me2AlCl, to form 2-alkenyl methyl sulfides with the elimination of COS. The reaction proceeds via a concerted, six-membered cyclic transition state, where the alkylthio group attacks the β-carbon of the allylic system, accompanied by a double bond shift. This thermally allowed pericyclic process is significantly accelerated by Lewis acid catalysts, enabling high-yield sulfide formation at room temperature. Molecular orbital calculations confirm the lowered energy barrier in the presence of AlCl3 while retaining the concerted mechanism.

40515-45-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40515-45-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,1 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.Calculate Digit Verification of CAS Registry Number 40515-45:
(7*4)+(6*0)+(5*5)+(4*1)+(3*5)+(2*4)+(1*5)=85
85 % 10 = 5
So 40515-45-5 is a valid CAS Registry Number.
