Benzo[b]thiophene, 2,3-dihydro-2,3-dimethyl- is an organic compound with the chemical formula C10H12S. It is a derivative of benzo[b]thiophene, a heterocyclic aromatic compound consisting of a benzene ring fused to a thiophene ring. The 2,3-dihydro-2,3-dimethyl substitution refers to the presence of two methyl groups (CH3) attached to the carbon atoms at positions 2 and 3, and the dihydro prefix indicates that the molecule has two additional hydrogen atoms, making it a partially saturated version of benzo[b]thiophene. Benzo[b]thiophene, 2,3-dihydro-2,3-dimethyl- is known for its potential applications in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals due to its unique structure and properties.

6383-18-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6383-18-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,8 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6383-18:
(6*6)+(5*3)+(4*8)+(3*3)+(2*1)+(1*8)=102
102 % 10 = 2
So 6383-18-2 is a valid CAS Registry Number.

MECHANISM OF THE THIO-CLAISEN REARRANGEMENT OF 3-METHYLALLYL PHENYL SULFIDE

Danilova, T. A.,Aukharieva, R. G.,Petrov, S. N.,Grobovenko, S. Ya.,Viktorova, E. A.

, p. 883 - 886 (2007/10/02)

The thio-Claisen rearrangement of isomeric 3- and 1-methylallyl phenyl sulfides was investigated.It is demonstrated that the thio-Claisen rearrangement of the 3-methyl isomer is preceded by its thioallyl rearrangement to the 1-methyl isomer.The latter undergoes thio-Claisen rearrangement to o-(3-methylallyl)thiophenol, which is cyclized to 2-ethyl-2,3-dihydrobenzothiophene and 2-methylthiochroman under the reaction conditions.
