1,3,5-tris-tert-butyl toluene is an organic compound with the chemical formula C19H30. It is a derivative of toluene, where three tert-butyl groups (C4H9) are attached to the 1, 3, and 5 positions of the benzene ring. This molecule is characterized by its symmetrical structure and high molecular weight, which contributes to its stability and resistance to chemical reactions. It is a colorless, crystalline solid with a melting point of around 180°C. Due to its bulky and non-polar nature, 1,3,5-tris-tert-butyl toluene is often used as a reference compound in various chemical studies and as a stabilizer in the production of certain polymers.

Check Digit Verification of cas no

The CAS Registry Mumber 1222-01-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,2 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1222-01:
(6*1)+(5*2)+(4*2)+(3*2)+(2*0)+(1*1)=31
31 % 10 = 1
So 1222-01-1 is a valid CAS Registry Number.

Steric Influence on Reactions of Benzyl Potassium Species with CO

Wang, Tongtong,Xu, Maotong,Jupp, Andrew R.,Qu, Zheng-Wang,Grimme, Stefan,Stephan, Douglas W.

supporting information, p. 3640 - 3644 (2021/10/19)

Reactions of benzyl potassium species with CO are shown to proceed via transient carbene-like intermediates that can undergo either dimerization or further CO propagation. In a sterically unhindered case, formal dimerization of the carbene is the dominant reaction pathway, as evidenced by the isolation of ((Ph3SiO)(PhCH2)C)2 2 and PhCH2C(O)CH(OH)CH2Ph 3. Reactions with increasingly sterically encumbered reagents show competitive reaction pathways involving intermolecular dimerization leading to species analogous to 2 and 3 and those containing newly-formed five-membered rings tBu2C6H2(C(OSiR3)C(OSiR3)CH2) (R=Me 6, Ph 7). Even further encumbered reagents proceed to either dimerize or react with additional CO to give a ketene-like intermediates, thus affording a 7-membered tropolone derivative 14 or the dione (3,5-tBu2C6H3)3C6H2CH2C(O))2 15.
