This annelation reaction was also investigated for the 4-bromo-5-ethylthio- and 4-bromo-5-phenylthio-2(5//)-furanones 186 in which the presence of the halogen atom in position 4 of the furanone ring could favor the formation of an-thraquinone derivatives (Scheme 52) (97T1823). Actually, the reaction of the... [Pg.137]

Thioglycosides were first introduced in glycosidation reactions by Ferrier in 1973 [31], who used the ethylthio group at the anomeric position. Subsequently, Hanessian [32] demonstrated the usefulness of the 2-pyridylthiol. Currently, the phenylthio and the ethylthio carbohydrate derivatives are the most commonly used glycosyl donors from this class of... [Pg.317]

Preparation of ethylthio-138 and phenylthio-carbene complexes139 was similarly achieved by treatment of the corresponding isolated tetrabutylammonium acylate complexes in CH2C12 at 40 °C with acetyl chloride, then with the corresponding thiols at 0 °C as illustrated in equation 64 for the phenylthio derivatives.

Unknown until recently, 2-(4-ethylthio)- and 2-(4-phenylthiophenyl)-pyrroles (8,9) are formed in a yield of up to 48% by the reaction of 4-ethylthio- and 4-phenylthio-acetophenone oximes with acetylene under atmospheric pressure at 96°C (Scheme 7) [90ZOR(ip)]. [Pg.212]

The anodic oxidation of 2,2-bis(ethylthio)propane producing acetone and an oxidation product of diethyl disulfide, claimed to be the corresponding disulfoxide, was reported many years ago [133]. A renewed interest in this reaction involving a C-S bond cleavage arose when bis(phenylthio)methane and some of its p-substituted ring derivatives were anodically oxidized in dry MeCN on Pt electrodes and afforded diaryl disulfides and formaldehyde, with the latter identified after aqueous workup [39, 134]. The same cleavage was observed when MeCN-H20 (9 1 v/v) was the solvent, but aryl benzenethiosulfonates were the main products [39] ... [Pg.648]
