Arbuzov-type reaction of acylphosphonites and N-alkoxycarbonylimine cations generated in situ with trifluoroacetic anhydride

Tetrahedron Letters, 2012
Abstract A mild procedure for the synthesis of N-protected α-aminoalkylphosphinic acids by the reaction of N,N′ -benzylidene- or N,N′ -alkylidenebiscarbamates, trifluoroacetic anhydride and the corresponding alkylphosphonous acids in methylene chloride or toluene is described.

Formation of amino-substituted phosphinyliron complexes [(.eta.5-C5H5)(CO)2Fe{P(O)(NR2)n(OR')2-n}] (n = 1, 2) by the Arbuzov-like dealkylation reaction

Organometallics, 1989
The reaction of (η 5 -C 5 H 5 )(CO) 2 FeCl with stoichiometric amounts of monoamino- and diamino-substituted oxyphosphines, P(NR 2 ) n (OR') 3−n (n=1, 2), generates the isolable cationic oxyphosphine iron complexes as chloride salts, [(η 5 -C 5 H 5 )(CO) 2 Fe{P(NR 2 ) n (OR') 3−n }] + Cl − . The monoaminooxyphosphine iron complexes undergo the Arbuzov-

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)].
