Abstract: Processes are provided for producing organchlorosilanes and dipodal silanes in which an organic halide or alkene or chloralkene is reacted with a hydridochlorosilane in the presence of a quaternary phosphonium salt catalyst by providing sufficient heat to effect a dehydrohalogenative coupling reaction and/or a hydrosilylation reaction and venting the reaction to control reaction pressure and to remove gaseous byproducts from the reaction. The processes are preferably continuous using a catalyst in fluid form at reaction pressures not exceeding about 600 psi. The reactions may be carried out substantially isothermally and/or isobarically, for example in a plug flow reactor or continuous stirred tank reactor. The processes may produce novel silylated compounds including 1,2-bis(trichlorosilyl)decane or 1,2-bis(trimethoxysilyl)decane.

Abstract: A guest host assembly comprising a host assembly formed of calixarene molecules and a guest component located within the host assembly. A crystallographic assembly of layers of the calixarene molecules and stacked along the crystallographic c axis of the assembly in a repeating configuration associated together predominantly by van der Waal forces. The guest component is transferable through the host assembly in a direction normal to the stacked layers. The calixarene molecules are configured in bilayers of adjacent layers along the c axis. The bilayers are shifted along the a or b axis so the assembly, relative to a corresponding assembly of the calixarene molecules without the inclusion of the guest component is shifted. The calixarene are calix(N)arenes in which N is an integer within the range of 4–8. The calixarene molecules are distally substituted with a substituent such as methyl, ethyl, propyl, butyl amyl or phenyl groups.
