Lithiated γ-O-functionalized propyl phenyl sulfides and sulfones of the type Li[CH(SOxPh)CH2CH2OR] (x=0, 2). [Li{CH(SPh)CH2CH2Ot-Bu}(tmeda)] – A structurally characterized organolithium inner complex

Reactivity of α‐Bromosulfones Obtained from gem‐Dibromides

“…Chelation of lithium in 33 by the methoxy group would generate an unfavorable sulfone gauche interaction. The mechanistic rational is supported by X‐ray crystal structure analysis of a related lithiated sulfone in which a direct Li–C bond and intramolecular Li–O coordination was observed 17,18…”

Rhodium(I) complexes with κP coordinated ω-phosphinofunctionalized alkyl phenyl sulfide, sulfoxide and sulfone ligands and their reactions with sodium bis(trimethylsilyl)amide and Ag[BF4]

“…4. Type II ligands with a C 3 spacer (n ¼ 3) are found to form organorhodium intramolecular coordination compounds (22,23) irrespective of the nature of the sulfur functionalization (x ¼ 0e2) [24,29]. In the case of the sulfinylfunctionalized ligands (x ¼ 1) the deprotonation of the prochiral CH 2 group creates a second chiral center; noteworthy, the formation of the respective organorhodium complexes (22b, 23b) proved to be diastereoselective.…”

One‐Pot Catalyst‐Free Synthesis of β‐ and γ‐Hydroxy Sulfides Using Diaryliodonium Salts and Microwave Irradiation

“…[1] β-and γ-Hydroxy sulfides are important organic intermediates that possess various applications; they have been used in the synthesis of biologically active compounds that show anticancer, anti-HIV, and 5-HT binding properties; [2] they have been used in the synthesis of crown ether ring-fused uridine analogs [3] and aryl vinyl sulfones; [4] they can be used as base protecting groups for thymidine analogs [5] and in the construction of natural products, [6] metallophthalocyanines, [7] organolithium complexes, [8] and α,β-unsaturated lactones.
