A utility for organoleads: Selective alkyl and aryl group transfer to tin

Me4Pb and Ph4Pb readily transfer methyl or phenyl groups to an equivalent molar ratio of tin(iv) chlorides in the order SnCl4 > MeSnCl3 > Me2SnCl2 > Me3SnCl, often in a selective manner. Me3PbCl and Ph3PbCl specifically transfer a single methyl/phenyl group under the same reaction conditions to produce recovered yields in >75%. Specific transfer of 2 methyl groups from PbMe4 can be achieved at elevated temperatures and/or a 2:1 molar ratio Pb:Sn.

Stannyl-Lithium: A Facile and Efficient Synthesis Facilitating Further Applications

We have developed a highly efficient, practical, polycyclic aromatic hydrocarbon (PAH)-catalyzed synthesis of stannyl lithium (Sn-Li), in which the tin resource (stannyl chloride or distannyl) is rapidly and quantitatively transformed into Sn-Li reagent at room temperature without formation of any (toxic) byproducts. The resulting Sn-Li reagent can be stored at ambient temperature for months and shows high reactivity toward various substrates, with quantitative atom efficiency.

Synthesis, structural characterization and antimicrobial activity of mixed aryl-alkyl diorganotin(IV) compounds with quinoline-2-carboxylate (L -): {RR'SnLCl}n and RR'SnL2

A series of unsymmetrical diorganotin derivatives of quinoline-2-carboxylic acid (LH), namely polymeric {MePhSnClL}n (1) and {EtPhSnClL} n (2), and mononuclear MePhSnL2 (3) and EtPhSnL 2 (4), was synthesized by the reaction of LH with the MePhSnCl 2, EtPhSnCl2, MePhSnO, and EtPhSnO precursors, respectively. The compounds were characterized by elemental analysis and infrared spectroscopy, as well as by 1 H, 13 C and 119Sn NMR. The molecular structures of representative compounds 2 and 4 were determined by single-crystal X-ray crystallography. This study showed that polymeric 2 adopts a distorted octahedral geometry as the carboxylate ligand N,O chelates an Sn atom and at the same time bridges a neighbouring Sn atom via the second O atom, with the remaining sites being occupied by the Cl and two C atoms; the O atoms are trans to each other. The result of the μ2-bridging mode of L- is the formation of a supramolecular helical chain. Compound 4 adopts a skew-trapezoidal bipyramidal geometry with the organo groups lying over the plane of the two N,O-chelating carboxylate ligands and being directed over the weaker Sn-N bonds. The in vitro antimicrobial activities of 1-4 against a Gram-positive bacteria strain (Bacillus subtilis), a Gram-negative bacteria strain (Escherichia coli) and against Candida albicans were studied and compared with the antimicrobial activities of Ph2SnL2 and Me2SnL2, and with the antimicrobial standards gentamicin, tetracycline, ampicillin and penicillin. All organotin compounds displayed remarkable antibacterial activities that were comparable to those of the standard drugs, in particular against B. subtilis, where the activity was correlated with the number of Cl substituents.

Strategies for the synthesis of bi- and triarylic materials starting from commercially available phenols

A series of arylstannanes have been synthesized, through an SRN1 mechanism, in good to excellent yields (74%-99%) by the photostimulated reaction of trimethyl stannyl ion with substrates supporting different nucleofugal groups. The arylstannanes thus obtained were suitable intermediates for Stille cross-coupling reactions leading to asymmetric bi- and triaryl compounds in acceptable global yields. An attractive feature of this route is that simple commercially available benzenediols, chloro- and methoxy phenols might be useful starting substrates, leading the latter to higher global yields of products in fewer steps. The strategies proposed open a broad synthetic tool.

Synthesis and reactivity of new κ2-[P,N]Pt(II) complexes of diisopropylphosphino-substituted 2-dimethylaminoindene

Treatment of 1-PiPr2-2-NMe2-indene (la[H]) with either czs/trans-(SMe2)2PtCl2 or PtCl2 provided (κ22-P,N-2-NMe2-3-P iPr2-indene)PtCl2 (2) in 84% and 55% yield, respectively, while the reaction of 1a[H] with (η4-COD)PtClMe afforded (κ2-P,N-2-NMe2-3-PiPr 2-indene)PtClMe (3) in 91% yield. Whereas in the formation of 2 and 3 the ligand precursor 1a[H] undergoes a rearrangement to give a coordinated 2-NMe2-3-PiPr2-indene (1b[H]) ligand, 1a[H] reacted cleanly with 0.5 equiv of [(μ-SMe2)PtMe2] 2 to give (κ2-P,N-1a[H])PtMe2 (4a) in 97% yield. The isomerization of 4a to (κ2-P,N-1b[H])PtMe 2 (4b) in a THF/iPrOH mixture is rapid and allowed for the isolation of 4b in 99% yield. Heating of 4a in CH2Cl2 resulted in the quantitative formation of 3, while the thermolysis of 4a in toluene in the presence of SMe2 afforded 5, the apparent product of intramolecular C-H activation of an NMe group. The reactivity of 4a with a variety of other two-electron donors, as well as E-H-containing substrates (E = main group fragment), is reported. Although NMR spectroscopic evidence indicated the formation of an intermediate of the type (κ2-P,N-1[H]) Pt(SnPh3)(Me), as well as Ph6Sn2, in the reaction of 4a with 10 equiv of Ph3SnH, negligible conversion of Ph3SnH to Ph6Sn2 was obtained when employing 1 mol % 4a as a catalyst. Single-crystal X-ray diffraction data for 2 and 5 are reported.

Reaction of trimethylaluminium with main group hydroxides: A non-hydrolysis route to methylalumoxane

Reaction of AlMe3 with [(tBu)2Ga(μ-OH)]3 or Ph3EOH (E = Sn, Pb) yields catalytically active MAO, [MeAlO]n, along with (tBu)2GaMe and Ph3EMe, respectively, in contrast, the reaction with Ph3EOH (E = C, Si, Ge) yields [Me2Al(μ-OEPh3)]2; the formation of MAO is proposed to occur via hydroxide exchange and the formation of unstable [Me2Al(μ-OH)]n; the propensity towards alkane elimination versus hydroxide exchange is controlled by the relative Bronsted acidity of the main group hydroxide.

Reactions of organolanthanide compounds RLnI (Ln = Yb, Eu, Sm) with organic derivatives of silicon, tin, lead, and antimony

Reactions of compounds RLnI (R = Alk, Ar; Ln = Yb, Eu, Sm) with hexaalkyl(aryl)-distannanes, trimethylsilyltriphenyltin, and lead and antimony acetates were studied. The reactions with Sn-Sn and Si-Sn organic derivatives result in cleavage of Sn-Sn amd Sn-Si bonds with formation of tetrasubstituted stannanes and reactive organometallic derivatives with an Sn-Ln or Si-Ln bond. The reactions of RYbI with lead and antimony acetates and with tetraethoxysilane cause cleavage of the Pb-O, Sb-O, or Si-O bond with formation of tetrasubstituted derivatives of lead and silicon or trisubstituted antimony derivatives.
