Expanding the Scope of Sulfur-Centered Arbuzov Rearrangement in Diethyl/Di-n-propyl Sulfite for the Synthesis of Mixed-Ligand Di-n-butyltin Alkanesulfonates

Inorganic Chemistry, 2006
A one-pot reaction between di-n-butyltin oxide and diethyl/di-n-propyl sulfite in the presence of an equimolar amount of alkyl iodide proceeds via sulfur-centered Arbuzov rearrangement to afford the corresponding di-n-butyltin (alkoxy)alkanesulfonates n-Bu2Sn(OR')OS(O)2R [R = R' = Et (1), n-Pr (2); R = Me, R' = Et (3), n-Pr (4)].

ChemInform Abstract: Formation of Amino‐Substituted Oxophosphorane Iron Complexes ((η5‐C5H5)(CO)2Fe(P(O)(NR2)n(OR′)2‐n)) (n = 1, 2) by the Arbuzov‐Like Dealkylation Reaction.

ChemInform, 1990
AbstractThe reaction of the chloro‐iron complex (I) with stoichiometric amounts of the phosphines (II) generates the isolable cationic complexes (III), which undergo an Arbuzov‐like dealkylation to the iron‐phosphonate complexes (IV) and (V).

Synthesis of chlorinated fullerenes C 60 Cl n (n = 2, 4) from C 60 Cl 6 and their Arbuzov-type reaction with P(OEt) 3

Tetrahedron Letters, 2018
Abstract Reduction of C60Cl6 with triphenylphosphine was demonstrated to be a useful method for the preparation of a mixture of low-chlorinated fullerenes C60Cln (n = 2, 4). Individual chlorofullerene 1,4-C60Cl2 was isolated by preparative gel permeation chromatography and characterized spectroscopically for the first time.

Reactions of Dimethyl Sulfite with Diorganotin Oxides. One-Pot Synthesis of Methoxydiorganotin Methanesulfonates through the Arbuzov Rearrangement, Spectroscopic Characterization of These Compounds and Their Derivatives, and X-ray Crystal Structures of n-Bu₂Sn(X)OS(O)₂Me (X = acac, bzbz, OH)

Inorganic Chemistry, 1999
One-pot reactions of diorganotin oxides, R(2)SnO, with dimethyl sulfite under reflux conditions (125-127 degrees C) proceed via the Arbuzov rearrangement at the sulfur center, yielding the corresponding methoxydiorganotin methanesulfonates, R(2)Sn(OMe)OS(O)(2)Me [R = n-Pr (1), n-Bu (2), i-Bu (3), c-Hx (4)], as white, hygroscopic solids. These compounds

Additive‐Free Phosphonylation of Chloroheteroarenes via S _N Ar–Arbuzov Reaction: Scope and Limitations

European Journal of Organic Chemistry
The phosphonylation of electron‐deficient alpha‐chloro‐substituted nitrogen‐containing heteroarenes with triethyl phosphite and triisopropyl phosphite using microwave‐assisted S N Ar–Arbuzov reaction was studied. The reaction proceeds at 200–270°C in 30–75 min.

Synthesis of Unsymmetrical Bis(Phosphine) Monoxides and N‐Heterocyclic Carbene‐Phosphine Oxides through Michaelis–Arbuzov Reactions of Phosphinite Esters

European Journal of Organic Chemistry
A modular synthesis of bis(phosphine) monoxide (BPMO) ligands has been realized using the Michaelis–Arbuzov reaction of dialkylphosphinite esters. The modular synthetic method allows the chemoselective synthesis of BPMO ligands in which the substituents on the two phosphorus centers are different.
