“…[52][53][54][55][56][57] Unlike carbon compounds, organosilicon compounds have the potential to increase their coordination number to 5-and 6-coordinated Si centers and have been characterized by X-ray and nuclear magnetic resonance (NMR) spectroscopy. [58][59][60] Unfortunately, the weak Si/X interactions reported for stabilizing the particular conformations of small molecules in these pseudocoordinations are difficult to characterize by routine spectroscopic methods.…”

Strong chemical forces such as covalent and ionic bonds are responsible for building discrete molecules, nature dwells on noncovalent forces weaker by three orders in magnitude, like the hydrophobic effect, hydrogen bonding, and van der Waals forces. Despite being weak, they possess the potential to drive spontaneous folding or unfolding of proteins and nucleic acids and the recognition between complimentary molecular surfaces. The power of these forces lies in the cooperativity with which they act, thereby generating a cumulative effect of many bonding interactions occurring together. Many ongoing research aims to translate the potential of these forces to the synthetic world to create desired structures with specific chemical functions. Achieving this offers unlimited opportunities for designing and synthesizing the most complex structures with specific applications. This highlight aims to reflect the critical role these noncovalent forces play in controlling macromolecular structures, which hold immense untapped potential for applications defying conventions, and briefly touches on the concept of homochirality in nature based on chiral and weak noncovalent interactions in synthetic nonpolar Si‐catenated polymers. It sheds some light on the discovery and characterization of Si/F‐C interactions in fluoroalkylated polysilanes in chemosensing of fluoride ions and nitroaromatics with a great sensitivity and selectivity. © 2008 Wiley Periodicals, Inc.

“…Very recently this trans-dibromide was obtained from reaction mixture yielded by the treatment of a mixture Z-and E-(EtO) 3 GeC(Br) C(Br)Ph (17) with N(CH 2 CH 2 -OH) 3 (TEA) (Eq. 6) [19].…”

“…Studies concerning transformations of substituent at the element atom have so far been very limited. 43 Earlier we reported that the treatment of N(CH 2 CH 2 O) 3 GeC CPh (1) with NBS/DMSO system affords N(CH 2 CH 2 O) 3 GeCBr 2 C(O)Ph and the reaction with bromine leads to the formation of cis-N(CH 2 CH 2 O) 3 GeC(Br) C(Br)Ph [7]. In contrast to this most of alkylatylacetylenes react with bromine in chloroalkanes under conditions of kinetic control to give a mixture of cis-and trans-dibromoalkenes, the latter considerably prevailing [8,9].…”

Complete geometry optimizations using ab initio SCF/3‐21G* calculations were performed on silatrane and azasilatrane, on their fluoro derivatives, and on methylsilatrane. By comparison with optimized geometries obtained for a series of model systems, the predicted transannular internuclear distances were interpreted in terms of the combined effects of electronegative substituents on Si and the anomeric interaction in the silatranes. The predicted geometries indicate that there is a weak transannular interaction in silatrane and a more significant one in azasilatrane, the predicted equilibrium distances being 2.66 and 2.15 Å, respectively. © 1996 John Wiley & Sons, Inc.
