The e-book is particularly well-written , with only a few typographical or grammatical mistakes, and the schemes and buildings are awarded in actual fact and esthetically.....
Overall, the authors offer transparent, powerfuble, and important assurance of the identify compounds. The hugely really good nature of the topic will most probably restrict the readership of this monograph, however it will turn out worthy to people with pursuits in organochalcogen chemistry and is suggested for inclusion in chemistry libraries.

Five synthetic methods have been developed for the sulfur derivatives 87 (E=S),: (1) R¢3SnSLi [275–277] or R¢3SnSNa+RCOCl ; (2) R2SnO  or RSn(O)OH  with RCOSH; (3) PhC(S)OAr with (n-C4H9)3SnH ; and (4) RxSnX4–x (X=halogen; x=0–3) with alkali metal or piperidinium thiocarboxylates [143, 271, 303]; (5) CH3COOSn(CH3)3  or (CH3COO)4Sn +CH3COSH . Amongst these methods, methods (1) (using lithium organotinthiolate) and (4) (using potassium thiocarboxylates) are the most practical from the point of view of good yields and simple procedures.
Kato · O. Niyomura tion with thioacetic acid leads to a quantitative yield of Tl(I) thioacetate . The compound 82 has been used as the starting compound for the preparation of thiocarboxylato niobium and tantalum complexes . Heating of 82 produces dibenzoyl disulfide and Tl(I) thiobenzoate . 1 Silicon In 1966 Martel and Duffaut  and Gronowicz and Ryan  reported the first synthesis of O-triorganosilyl thiocarboxylates 83b from reacting thiocarboxylic acids with triorganosilyl chlorides or triorganosilylamines, respectively.
The chemistry of this class of compounds, however, is not 36 S. Kato · O. Niyomura known. The reaction of CuCl or Cu(CH3COO)2 with thiobenzoic acid  and its sodium  or triethylammonium salts  results in yellow-green diamagnetic thiobenzoato copper(I) Cu(C6H5COS). Its molecular structure analysis by X-ray diffraction remains to be done. 9,10-Phenanthrenesemiquinonatobis(triphenylphosphine)copper(I) readily reacts with dibenzoyl disulfide to give the dinuclear Cu(I) complex 60, in which the thiobenzoato ligand is monodentate and bridges between the two copper ions .
