The first titanium(IV) complexes with cyclic tetrasiloxide ligands, [Ti(L1H)(OSiMe3)]2(H2O) (1) and (CpTiCl)4(L2)2 (2), were synthesized using the all-cis isomer of cyclotetrasiloxanetetraols R4(Si...
studies on thermostable materials, heptacyclicladdersiloxanes and ladderpolysilsesquioxane were synthesized. The first heptacyclicladdersiloxanes were obtained by chlorination of pentacyclic laddersiloxanes prepared using our stereocontrolled synthesis procedure; thereafter, the heptacyclicladdersiloxanes were made to react with disiloxanediol. Ladderpolysilsesquioxane was obtained from cis–trans–c
