ORIGINAL REACTIONS OF α,α-DITHIO ARYL ALKANES WITH BUTYLLITHIUMS
Krief, Alain,Kenda, Benoit,Barbeaux, Philippe
, p. 2509 - 2512 (2007/10/02)
Thioacetals derived from aromatic ketones react with butyllithiums already at -78 deg C and produce via a reductive process the corresponding α-thiobenzyllithiums in high yields.The same reaction also takes place selectively, under suitable conditions, wi
