Siloxanes have evolved into a multi‐million dollar business due to their manifold of
commercial and industrial applications. As siloxanes have high hydrophobicity, low basicity …

Some scientists might consider group 2 chemistry as “boring, closed shell and all ionic,
aqueous chemistry, where everything is known! It is not worth investigating”. How wrong …

Covalency and ionicity are orthogonal rather than antipodal concepts. We demonstrate for
the case of siloxane systems [R3Si−(O− SiR2) n− O− SiR3] that both covalency and ionicity …

Simple silyl ethers like O (SiMe3) 2 in contrast to normal ethers are inert to metal bonding;
however, a “naked”, highly Lewis-acidic, cationic Mg species enforces complexation. DFT …

In this study we present a (re-) investigation into cyclodimethylsiloxanes in relation to silyl-
ether bonding towards alkali metal ions. We demonstrate that all (non-radioactive) alkali …

Through reactions of 1, 2-disila [12] crown-4 or 1, 2-disila-benzo [12] crown-4 ethers with
BeCl2 eight-membered Be–O-heterocycles, which are annulated by two six-membered Be …

Alkaline earth metal catalysis has been a growing field in recent years. To enhance reactivity
and to understand the metal-substrate interactions in more detail, reactions are increasingly …

Herein we present the synthesis and coordination chemistry of the partially silicon based
crown ether analogues 1, 2, 4, 5-tetrasila-benzo [15] crown-5 (1) and 1, 2, 4, 5-tetrasila [18] …

We present the coordination chemistry of the cyclodimethylsiloxanes D6 and D7 toward
alkaline earth metal salts. The coordination chemistry of these macrocycles toward alkaline …

We herein report the synthesis, structures, coordination ability, and mechanism of formation
of silicon analogs of crown ethers. An oligomerization of 2D2 (I)(2Dn,=(Me4Si2O) n) was …
