Two known tin-based polymers of formula {[R3 Sn(CH3 COO)]n} where R = n-Bu– (1) and R = Ph– (2),were evaluated for their in vitro biological properties. The compounds were characterized via their physical properties and FT

Page/Page column 34, (2009/07/25)
An object of the present invention is to provide a process for producing a dialkyl tin compound from a composition of deactivated forms of a dialkyl tin catalyst, and to provide a process for producing the dialkyl tin catalyst from the dialkyl tin compound and using the dialkyl tin catalyst to produce a carbonic acid ester. According to the present invention, a process for producing a dialkyl tin compound is provided that subjects a composition of the deactivated forms of the dialkyl tin catalyst, formed when producing an ester compound, to an alkyl group redistribution reaction and/or dealkylation reaction.
RADICAL TRAP IN FLUORIDATION OF IODONIUM SALT
-
Page/Page column 24-25, (2008/06/13)
Decomposition of iodonium salts by a free radical process has been identified as a significant factor in the observed yield variability of fluoridation reactions using said iodonium salts. Accordingly, the inclusion of a free radical trap in the reaction mixture blocks the radical chain decomposition pathway for iodonium salts such that only the reaction leading to fluoridation can occur and the yield of aryl fluoride becomes high and reproducible. The reaction may also be carried out on solid phase. In both the solution and the solid phase the preferred method of the present invention is radiofluoridation.

The reaction of dimethyl(phenyl)silanol with butyl acrylate in the presence of a stoichiometric amount of Pd(OAc)2 or by a combined use of 0.1 molar amount of Pd(OAc)2 and Cu(OAc)2/LiOAc (molar ratio 3/2) gave butyl cinnamate in 76% or 57% yield, respectively. The similar reaction with tributyl(phenyl)tin also proceeded in 77% yield. The organotin compound was shown to react faster than the sitanol, although the tin reagent sometimes induced undesirable homocoupling, while the reaction with silanol did not give such by-product.
Reactions of Organoytterbium Compounds RYbI (R = Me, Et, Ph) with Organotin Oxides and Acetates
Rybakova, L. F.,Syutkina, O. P.,Novgorodova, M. N.,Petrov, E. S.
, p. 85 - 87 (2007/10/03)
Reactions of RYbI (R = Me, Et, Ph) with organotin oxides and acetates) involve cleavage of the Sn-O bonds to form tetrasubstituted stannanes mostly as single or main reaction products (yields 65-96 percent). A similar results was obtained in reaction of PhYbI with diphenyltin sulfide (yield 93 percent). However, reactions of RYbI (R = Me, Et, Ph) with Bu2SnO, followed by hydrolysis of the reaction mixtures lead to hydroxystannanoxanes Bu2RSnOH in 66-75 percent yields.
New latent organotin catalysts: Preparation and mechanism of the thermal decomposition of bis(2-(acyloxy)alkyl)diorganotins

, p. 1330 - 1331 (2008/10/08)
New organotin compounds, bis(2-(acyloxy)alkyl)diorganotins, can be thermally decomposed into diorganotin dicarboxylates. The substituent effects on the reaction parameters are studied, and a possible mechanism for the decomposition is proposed. These tetr

, p. 221 - 222 (2007/10/02)
The oxidative substitution reaction of olefinic tin compounds with lead tetraacetate(LTA) was investigated.The oxidation is highly regioselective and gave a dipole inversed product (acetate) in good yield.
THE CHEMISTRY OF ORGANOLEAD(IV) TRICARBOXYLATES. SYNTHESIS AND ELECTROPHILIC HETEROARYLATION REACTIONS OF 2- AND 3-THIENYL-, AND 2- AND 3-FURYL-LEAD
Pinhey, John T.,Roche, Eric G.
, p. 2415 - 2422 (2007/10/02)
Tin(IV)-lead(IV) exchange and mercury(II)-lead(IV) exchange reactions have been used to obtain 2-thienyl-lead triacetate (3), 2-thienyl-lead tribenzoate (4), 3-thienyl-lead triacetate (16), 2-furyl-lead triacetate (21), and 3-furyl-lead triacetate (31).In reactions with the β-dicarbonyl compounds (7), (11), and (13), the above heteroaryl-lead compounds behaved as 2-thienyl, 3-thienyl, 2-furyl, and 3-furyl cation equivalents respectively, giving the α-heteroaryl β-dicarbonyl compounds (8), (12), (14), (17), (18), (19), (25), (27), (28), (38), (34), and (35) in synthetically useful yields.
α-Alkenylation of β-Dicarbonyl Compounds with 'Alk-1-enyl-lead Triacetates'
Moloney, Mark G.,Pinhey, John T.
, p. 965 - 966 (2007/10/02)
Addition of lead tetra-acetate to a chloroform solution of a dialk-1-enylmercury or an alk-1-enyltributylstannane results in rapid formation of a relatively unstable species, believed to be an alk-1-enyl-lead triacetate, which can be used for the α-alkenylation of β-dicarbonyl compounds.
