Summary

The reaction of Al2Cl6 with an excess of Ph2Si(OH)2 in THF in the presence of pyridine yielded new anionic and cyclic aluminosiloxanes. Interactions of Al(Et)3 with Ph2Si(OH)2 in a 1:2 ratio respectively yielded an ALt(OH)4 eight-membered ring in a molecular aluminopolysiloxane. Another reaction involving A12Cl6 with two trisilanols (c-C6H11)7Si7O9(OH)}3 in diethyl ether assisted by NEt3 yielded the anionic complex [HNEt3]{Al{(c-C6H11)7Si7O11(OH)}2] with two free OH functionalities.
