Summary. The synthesis of cyclic polysiloxanes of the general formula (OSiX 2) n with X=halogen, nitrogen, or oxygen centered ligand is achieved using a new strategy of assembling difunctional entities. The actual progress in this field is reviewed. Furthermore, polysiloxanes are described in which at distinct locations the silicon atoms are replaced by aluminum to which hydroxide groups are attached. The central molecule of interest has the formula [(Ph2Si)2O3Al(OH)]4, and its reactions with bases like diethylether, triethylamine, or pyridine are discussed following ideas of host-guest chemistry. Reaction of [(Ph2Si)2O3Al(OH)]4 with lithium organyls are also reviewed.
