Reactions of 2,4,6-Tri-t-butylphenyllithium with O-Alkyl Selenoformates: Intermediate Formation of 2,4,6-Tri-t-butylselenobenzaldehyde

2,4,6-Tri-t-butylphenyllithium reacts with O-alkyl selenoformates (1) at three different sites (i.e., the selenoformyl carbon, the selenoformyl hydrogen, and the selenium) to give 1,3,5-tri-t-butylbenzene, 2,4,6-tri-t-butylbenzaldehyde, 6,8-di-t-butyl-3,4-dihydro-4,4-dimethyl-1H-2-benzoselenin (11), bis(2,4,6-tri-t-butylphenylmethyl) di(and tri) selenides, bis(2,4,6-tri-t-butylphenyl) diselenide, and dibutyl diselenide depending on the reaction conditions and the alkyl group in 1.The formation of 11 is explained in terms of the intermediacy of 2,4,6-tri-t-butylselenobenzaldehyde, which is trapped by condensation rection with butylamine leading to N-(2,4,6-tri-t-butylbenzylidene)butylamine.Mechanism for the formation of these products is also discussed.

Abnormal Reaction of 2,4,6-Tri-t-butylphenyl-lithium with Selenoformates: Possible Intermediacy of Selenobenzaldehyde

The title reaction afforded some products strongly suggestive of the intermediacy of 2,4,6-tri-t-butylselenobenzaldehyde.

Reactions of 2,4,6-Tri-t-butylphenyllithium with Deuterated Formate, Thioformate and Selenoformate

O-Cholesteryl chalcogenoformates-d, DC(=X)(OR) (2: X=O; 3: X=S; 4: X=Se; R=3β-cholesteryl), were synthesized and allowed to react with 2,4,6-tri-t-butylphenyllithium. 1,3,5-Tri-t-butylbenzene was a main product in each reaction. The other products were 2,4,6-tri-t-butylbenzaldehyde-d (9) for 2, 2,4,6-tri-t-butylthiobenzaldehyde-d for 3, and 9, 6,8-di-t-butyl-1-deuterio-3,4-dihydro-4,4-dimethyl-1H-2-benzoselenin, bis(2,4,6-tri-t-butyl-α-deuteriobenzyl) diselenide, and bis(2,4,6-tri-t-butyl-α-deuteriobenzyl) triselenide for 4.The mechanisms for these reactions have been discussed.
