2,6-di-tert-butyl-8-methoxydibenzofuran-1,4-dione is a complex organic compound with the molecular formula C18H22O4. It is characterized by a dibenzofuran core, which is a fused ring system consisting of a benzene ring and a furan ring. The compound features two tert-butyl groups attached to the 2nd and 6th carbon atoms of the dibenzofuran, providing steric hindrance and stability. Additionally, a methoxy group is present at the 8th carbon, contributing to the compound's polarity. The 1,4-dione functional group, which consists of two carbonyl groups separated by a single carbon atom, is also a key feature of this molecule. This chemical structure endows the compound with unique properties, making it potentially useful in various applications, such as in the synthesis of pharmaceuticals or as a chemical intermediate.

Check Digit Verification of cas no

The CAS Registry Mumber 4950-33-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,5 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4950-33:
(6*4)+(5*9)+(4*5)+(3*0)+(2*3)+(1*3)=98
98 % 10 = 8
So 4950-33-8 is a valid CAS Registry Number.

One-pot synthesis of dibenzofuran- 1,4-diones 8 from 4-methoxyphenols (or 4-methoxy-1-naphthols) 4 was achieved by oxidative dimerization over a semiconductor in heated, O2-saturated toluene, followed by selective monodemethylation, and oxidati

OXIDATIVE COUPLING REACTION OF 2-HALOPHENOLS WITH K3Fe(CN)6 IN BENZENE SOLUTION

, p. 653 - 660 (2007/10/02)

The oxidative coupling of twelve 2-halophenols (1a-1l) was carried out with K3Fe(CN)6 in benzene solution to obtain the corresponding dibenzofuran derivatives.However, only a small amount of the desired dibenzofurans such as 2,6-di-tert-butyl-8-methoxybenzofuran-1,4-quinone (9) and 4,8-di-tert-butyl-2,6-di-isopropyl-1-hydroxydibenzofuran (11) were obtained from 2-bromo-6-tert-butyl-4-methoxy- (1d) and 2-bromo-4-tert-butyl-6-isopropylphenol (1g), respectively.In the other cases, alternative type of products or tarry materials were formed.
