Novel Desulphurization of Thiourea Derivatives by Alkaline Autoxidation
Kim, Yong Hae,Kim, Hyung Jin,Yon, Gyu Hwan
, p. 1064 - 1065 (1984)
Autoxidation of 1,3-disubstituted thioureas in the presence of oxygen and tertiary butoxide in tertiary butanol afforded the corresponding ureas in good yields together with small amounts of the corresponding guanidines while the same treatment of benz- or naphth-imidazole-2-thiones gave the parent imidazoles and the 2-sulphonic acids.

O-Iodoxybenzoic acid mediated oxidative condensation: Synthesis of guanidines using 1,-3-disubstituted thiourea precursors
Dangate, Prasad S.,Akamanchi, Krishnacharya G.
, p. 6765 - 6767 (2013/01/15)
An efficient and mild oxidative condensation procedure using o-iodoxybenzoic acid and triethylamine or ammonia as base has been developed for the synthesis of guanidines starting from easily synthesizable 1,3-disubstituted thioureas and amines or ammonia.
Benzenetellurinic Mixed Anhydrides as Mild Oxidizing Agents
Fukumoto, Takahiro,Matsuki, Toshiaki,Hu, Nan Xing,Aso, Yoshio,Otsubo, Tetsuo,Ogura, Fumio
, p. 2269 - 2272 (2007/10/02)
Three benzenetellurinic mixed anhydrides. i. e. benzenetellurinyl acetate, trifluoroacetate, and trifluoromethanesulfonate, have been found to be mild oxidizing agents for various substrates such as thiol, phosphine, acyloin, α-hydroxy ester, catechol, hydroquinone, thiourea, and thioamide.The reactions towards the last two substrates are highly chemoselective, depending on both the reagent and substrate.
