On the bonding in carbosilanes
WebAs a typical example carbosilane dendrimers up to the third generation containing a N,N′,N″-1,3,5-benzenetricarboxamide core (G1–G3) have been synthesized. This new class of molecules has been studied as host molecules and they have been found to bind protected amino acids as guest molecules via hydrogen bonding interactions. Web30 de mar. de 2024 · The OCS [ 9] was synthesized from a liquid carbosilane (LCS) in two steps: first at atmospheric pressure and then at a residual pressure of from 0.2 to 0.4 kPa according to the scheme. where m = 1–3, l = 1 or 2, and k = 6. The OCS synthesis conditions and the properties of the LCS are summarized in Table 1. Table 1.
