Cycloaddition and Oxidation Reactions of a Stable Thioaldehyde, (2,4,6-Tri-t-butyl)thiobenzaldehyde

The title thioaldehyde 1 undergoes [4 + 2] cycloaddition with 2,3-dimethyl-1,3-butadiene at 160°C and [3 + 2] cycloadditions with diphenylnitrilimine and mesitonitrile oxide at room temperature. The intermediary cycloadduct with mesitonitrile oxide undergoes cycloreversion to give 2,4,6-tri-t-butylbenzaldehyde and mesityl isothiocyanate as the final products. Oxidation of 1 with m-chloroperbenzoic acid (mCPBA) and dimethyldioxirane (9) gives a mixture of (E)- and (Z)-isomers of the corresponding S-oxides (sulfines), the former and the latter being kinetically and thermodynamically controlled products, respectively. Although both (E)- and (Z)-sulfines are not further oxidized by mCPBA, the (Z)-sulfine is oxidized with 9 to give 7-oxa-8-thia-2,4,6-tri-t-butylbicyclo[4.3.0]nona-2,4,9-triene 8,8-dioxide and 6,8-di-t-butyl-3,4-dihydro-4,4-dimethyl-1H-2-benzothiopyran 2,2-dioxide, both of which are intramolecular cyclization products of an intermediary thioaldehyde dioxide (sulfene).

Synthesis, Structure, and Some Reactions of (2,4,6-Tri-t-butyl)thiobenzaldehyde, the First Stable Aromatic Thioaldehyde

The title compound 1 was synthesized by the reaction of 2,4,6-tri-t-butylphenyllithium with O-ethyl thioformate or that of 2,4,6-tri-t-butylbenzaldehyde hydrazone with disulfur dichloride in the presence of triethylamine. The thioaldehyde 1 is a purple cr

Synthesis and Unusual Photochemical Reaction of Highly Congested 2,4,6-Tri-t-butylstyrene Episulfides

Title compounds were synthesized by the reaction of 2,4,6-tri-t-butylthiobenzaldehyde with some diazomethanes.The photolysis of the most sterically congested episulfide obtained from t-Bu2CN2 gave an unusual product resulting from 1,2-migration of t-butyl

Photoreaction of a Stable Thioaldehyde 2,4,6-Tri-tert-butylthiobenzaldehyde

The photochemical reaction of the only isolable aromatic thioaldehyde ArCHS (1; Ar=2,4,6-tri-tert-butylphenyl) in alkaline medium yields ArCH2CH2Ar (2), ArCH2SCH2Ar (3), 6,8-di-tert-butyl-3,4-dihydro-4,4-dimethyl-1H-2-benzothiine (4) and ArMe (5).A radica

REACTIONS OF A STABLE THIOBENZALDEHYDE WITH ORGANOMETALLICS

Rections of 2,4,6-tri-t-butylthiobenzaldehyde with Grignard and organolithium reagents gave products via the anion radical of the thioaldehyde.The first example of dimerization of thioketyl radicals was also presented.
