Metalated Oligosilanylstibines
The reaction of a cyclic disilylated bromostibine with magnesium yields a rare example of a magnesium stibide that can be silylated with trimethylchlorosilane. Reaction of the thus-obtained trisilylated stibine with potassium tert-butoxide gives a potassium stibide in a clean reaction. Attempts to obtain an antimony-containing oligosilanide did not lead to the expected compound but to another p...
متن کاملThe Bonding Situation in Metalated Ylides
Quantum chemical calculations have been carried out to study the electronic structure of metalated ylides particularly in comparison to their neutral analogues, the bisylides. A series of compounds of the general composition Ph3 P-C-L with L being either a neutral or an anionic ligand were analyzed and the impact of the nature of the substituent L and the total charge on the electronics and bon...
متن کاملReaction of metalated nitriles with enones.
[reaction: see text] There have been a number of reports of the kinetic conjugate (1,4) addition of metalated arylacetonitriles to enones. Several proposals have been made to explain this behavior based on nucleophile structure or aggregation state or on the HSAB properties of the reactants. A reexamination of these studies showed that in each case the 1,4 adducts resulted from equilibration of...
متن کاملTuning the Si–N Interaction in Metalated Oligosilanylsilatranes
Most known silatrane chemistry is concerned with examples where the attached silatrane substituent atom is that of an element more electronegative than silicon. The current study features silylated silatranes with a range of electropositive elements attached to the silyl group. The resulting compounds show different degrees of electron density on the silatrane-substituted silicon atom. This dir...
متن کاملCharge carrier dynamics in metalated polymers investigated by optical-pump terahertz-probe spectroscopy.
We report charge carrier dynamics in solid films of a series of metalated polymers based on Pt- and 4,7-di-2'-thienyl-2,1,3,-benzothiadiazole or 4,7-di-2'-thienothienyl-2,1,3,-benzothiadiazole upon photoexcitation of the pi-pi* transition using optical-pump terahertz-probe spectroscopy. Subpicosecond generated charge carriers recombine within 100 ps, but bound excitons persist. Application of t...
