Nucleophilic attack within Ge, Sn and Pb complexes containing Me2N(CH2)3—as a potential intramolecular donor ligand

The modification of bis(pyrazol-1-yl)methanes by chalcogen (S and Se) and their related reactions with organotin chloride and M(CO)5THF (M = Mo and W)

“…The Sn-N bond distance of 2.373(4) Å is similar with that in organotin derivatives containing anionic heteroscorpionate ligands, such as (3,5-Me 2 Pz) 2 CHCO 2 SnPh 2 Cl (av. 2.357 Å , Pz = pyrazol-1-yl) [26], but slightly shorter than those in organotin derivatives containing neutral bis(pyrazol-1-yl)methane ligands, such as CH 2 (4-MePz) 2 SnMe 2 Cl 2 (2.436 Å ) [21] and CH 2 (3-i PrPz) 2 SnPh 2 Br 2 (2.435 Å ) [27] as well as that in Me 2 N(CH 2 ) 3 SnPh 2 Cl (2.578(4) Å ) [28], and longer than the reported data for organotin derivatives containing anionic poly(pyrazol-1-yl)borate ligands [29].…”

A nitrogen-base catalyzed generation of organotin(ii) hydride from an organotin trihydride under reductive dihydrogen elimination

“…[73][74][75][76][77] However in the case of tetraorgano stannanes without electronegative substituents, indications for donor-acceptor interactions of amines with poorly Lewis acidic Sn is only found in constrained intramolecular arrangements partially leading to increased reactivities of the hydride. [78][79][80][81][82] The poor Lewis acidity may also be seen from the optical stability of chiral stannanes and tin hydrides even in the presence of bases. 83,84 On addition of some Lewis-bases triorganotin hydrides have been found to be more active hydride donors.…”

Validation of a Terminally Amino Functionalized Tetra‐Alkyl Sn(IV) Precursor in Metal–Organic Chemical Vapor Deposition of SnO2 Thin Films: Study of Film Growth Characteristics, Optical, and Electrical Properties

“…Precursor Synthesis : The metal–organic complex [Sn(DMP) 4 ] was not evaluated and employed as a precursor for chemical vapor deposition techniques so far, yet a procedure for its synthesis was reported . Hence, the compound was synthesized in large batches (≈10 g) employing an intermediately formed Grignard reagent according to the route of Zickgraf et al and was subjected to detailed thermal analysis, vapor pressure investigation, and application in CVD.…”
