- SYNTHESIS OF ORGANO CHLOROSILANES FROM ORGANOSILANES
-
The invention relates to a process for the production of chlorosilanes by subjecting one or more hydndosilanes to the reaction with hydrogen chloride in the presence of at least one ether compound, and a process for the production of such hydndosilanes serving as starting materials.

- Polysilanes Bearing a Phenoxypropyl Side Chain
-
A series of polysilanes bearing a 3-phenoxypropyl side chain was prepared applying the Wurtz coupling reaction of dichlorosilanes. All prepared polymers ([R-Si(CH2)3OPh]n, R = Me, Pent, Hex, Hept, (CH2)3/s

- Macrocyclic polyether compounds
-
Macrocyclic polyether "crown" compounds of the formula EQU1 WHEREIN T is a C2 -C3 alkylene, A is EQU2 R being H or C1 -C18 alkyl, R2 and R3 being independently C1 -C18 alkyl, C2 -C4 alkenyl, or C6 -C14 aryl; Q and Z are independently 1,2-arylene (or saturated derivatives thereof) or substituted 1,2-arylene (or saturated derivatives thereof); a is 0, 1, 2, or 3; b is an integer from 3 to 20; y is 1 or zero; x1, x2, x3, and x4 are integers independently selected to give a 15-60 atom ring. Such crown compounds are generally useful in the formation of complexes with ionic metal compounds, thus making it possible to use certain chemical reagents in media wherein they are normally insoluble.
