Dianions 2 of dithioacids 1 and carbon disulfide yield in a kinetically controlled reaction at -78 deg C S-adducts (e.g. 3, 13) or in a thermodynamically controlled reaction at room temperatur C-adducts .Acidification of 10 and subsequent reactions give rise to the tetrathiomalonic acids 18 and its derivatives 19 with 2,6,9,10-tetrathiaadamantane structure.Deprotonation of 10a leads to the tetrathiomalonic acid tetraanion (20) which may be alkylated to yield the tetrakis(alkylthio)allenes 21.By condensation of the dithioacid dianions 2, the tetrathiomalonic acid trianion 10 and the tetrathiomalonic a cid tetraanion (20) with 2,3-dichloro-1,4-naphthoquinone (32) a number of naphtho-1,3-dithiole-4,9-diones (e.g. 33, 35, 37) are obtained. - Key Words: Dithio acid dianions / Tetrathiomalonic acid / Anions / Tetrathiomalonic acid tetraanion / Dithioacrylic esters / Thio acids / Allenes, alkylthio- / Naphtho-1,3-dithiole-4,9-diones / Malonic acid, tetrathio- / Acrylic acid, dithio
Tetrathiomalonic acid and its anions
Hartke,Rettberg
, p. 4679 - 4682 (2007/10/02)
Condensation of ethanedithioic acid with CS2 and 3 Li[HMDS] leads to the trianion 13 which is protonated to give the dimer 17 of tetrathiomalonic acid. Further deprotonation of 13 leads to the tetraanion 19 which is alkylated to form the tetrak
