AbstractUpon reaction with the sodium alcoholates (II), the chloromethylsilatrane (I) rearranges by ring expansion, giving the alkoxy‐2‐carba‐3‐ oxa‐homosilatranes (III).
Reaction of alkali metal sucrates and alkoxides with 1-(chloromethyl)silatrane results in expansion of one of the atrane rings to give 2-carba-3-oxahomosilatranes.

AbstractDas Triethoxysilan (I) reagiert mit Triethanolamin (II) in Gegenwart von Kalilauge zum Silatran (III).
Aus der l‐O‐Acetyl‐2,3,5‐tri‐O‐benzoyl‐a‐D‐xylofuranose (I) und den bissilylierten Pyrimidinen (II) erhält man die Nucleoside der Xylofuranosylreihe (III).
The solubilization of precipitated complex of alpha-polyglucane-dimethyldodecylbenzylammonium chloride in excess of a solution of the salt was found to be dependent on pH. The complexes of glycogen having a more branching structure are dissolved much more readily than the amylopectin complexes. The conditions for separation of mixtures of these two alpha-glucanes were found. The purity of glycogen and amylopectin obtained after separation from the mixture was established both by comparing the absorption spectra of their iodinepolysaccharide complexes and by separation of radioactive amylopectin and non-radioactive glycogen mixture.
