Tin Two-Step Doubly and triply bonded carbon compounds have a well-studied tendency to link up with one another and form rings. The rates of these reactions and their relative susceptibilities to acceleration by heat versus light are encapsulated in the decades-old Woodward-Hoffmann rules. More recently, alkene and alkyne analogs have been prepared with heavier elements such as silicon and tin substituted for carbon. Peng et al. (p. 1668; see the Perspective by Sita) have now discovered that… Expand

The highly efficient, simultaneous addition of two molecules of ethylene (H2C=CH2) to a tin analog of acetylene: a distannyne, RSn≡SnR, where the R groups are bulky hydrocarbons is reported. Expand
A Novel Reactivity of Phosphanylalumane (>P-Al<): Reversible Addition of a Saturated Interelement Bond to Olefins.
The reversible addition reactions of olefins with a phosphanylalumane, P-Al single bond species, were investigated and the ethylene-adduct was found to undergo complexation with nitriles to give the corresponding nitrile adducts to the Al center, which retained the Ethylene-tether as in the case of the corresponding P/B-based FLP.

Oxidation of intramolecularly coordinated distannyne by S8: from tin(I) to tin(IV) polysulfide via tin(II) sulfide.
The investigation of heavier Group 14 element analogues of alkynes of the type (RE)2 (where E=Si, Ge, Sn, or Pb) is of current interest and showed that the presence of rather bulky substituents allowed the synthesis of RE ER, which possess multiple bonds. Expand
Reversible Oxidative Addition/Reductive Elimination of a Si-H Bond with Base-Stabilized Silylenes: A Theoretical Insight.
A theoretical study on the reaction of phosphine-stabilized silylenes with silanes that proceeds through reversible OA/RE at room temperature is reported, highlighting the important role of the ligand in the kinetics and energy balance of the reaction. Expand
Boron-mediated sequential alkyne insertion and C–C coupling reactions affording extended π-conjugated molecules
C–C bond coupling reactions illustrate the wealth of organic transformations, which are usually mediated by organotransition metal complexes. Here, we show that a borafluorene with a B–Cl moiety canExpand
Intramolecularly coordinated tin(II) selenide and triseleneoxostannonic acid anhydride.
Recently, it has been shown that the use of intramolecularly coordinating built-in N,C,N-coordinating pincer-type ligands is an alternative concept for the synthesis and stabilization of the reactive distannyne, and in the course of a systematic studies on the metal-type redox reactivity of 1, this compound showed the powerful reducing character of the tin(I) compound towards neutral cot.

Cleavage of the Sn-Sn multiple bond in a distannyne by cyclooctatetraene: formation of the pi-bound inverse sandwich complex [(Ar'Sn)2(mu2-eta2:eta3-cot)].
It is shown that the distannyne undergoes reversible complexation with two molecules of either ethylene or norbornadiene, processes that are considered symmetry-forbidden for alkynes but are enabled by the higher reactivity caused by the strained geometry in the heavier analogues. Expand
Reactivity of Boryl- and Silyl-Substituted Carbenoids toward Alkynes: Insertion and Cycloaddition Chemistry
Three modes of reactivity of phenyl-substituted alkynes toward acyclic tetrelenes are reported, with reaction pathways found to be dependent not only on the nature of the group 14 element but also onExpand
