1-(Benzothiazol-2-yl)-3-phenylthiourea 2 was prepared and treated with hydrazonoyl chlorides 3a-e to yield the corresponding 5-(benzothiazol-2-ylimino)-1,3,4-thiadiazole derivatives 6a-e, respectively. Reaction of the thiourea derivative 2 with ethyl 2-ch
Blue-light induced CO releasing properties of thiourea based manganese(I) carbonyl complexes
Mansour, Ahmed M.,Friedrich, Alexandra
, p. 13 - 21 (2017)
A new class of blue-light triggered carbon monoxide releasing molecules based on Mn(CO)3Br(N,S) ((N,S)?=?N,S-bidentate thiourea ligands) has been reported in this work. The 1H and 13C NMR analysis indicated that the thioureas coordinate to Mn(I) in the thione form. The stability test and the ability to derive CO to DMSO and myoglobin solution upon the exposure to 468?nm light source have been investigated. The benzothiazole-thiourea-CORM released only one CO equivalent, while the pyridine-analogs offered two molecules at the same experimental conditions. Natural bond orbital analysis has been carried out to give details about the hybridization of Mn–C and C[tbnd]O bonds, natural charge, electronic arrangement of metal ion and strength of interaction between Mn(I) and the coordination sites. Both functional, B3LYP and CAM-B3LYP compare well with the experimental findings, where the longest wavelength band is assigned to MLCT.
1,3-Di-n-butylimidazolium tribromide-mediated chemoselective oxidative cyclization of benzothiazoyl carbaimides: A novel approach toward the synthesis of N-bis-benzothiazole derivatives

experimental part, p. 342 - 348 (2012/06/15)
4-(N,N-Dimethylamino)pyridine is found to be an efficient catalyst for the synthesis of benzothiazoyl carbaimide derivatives using 2-aminobenzothiazoles and phenylisothiocyanates, which on treatment with ionic liquid [bbim][Br 3] at 70°C afforded exclusive formation of N-bis-benzothiazole derivatives in good yield.
