Silanetriols as Powerful Starting Materials for Selective Condensation to Bulky POSS Cages.
Ontology highlight
ABSTRACT: Controlled condensation reactions of tertiary silanetriols CH3(CH2) n (CH3)2CSi(OH)3 (1b-f; n = 1-5) in the presence of trifluoroacetic acid and the hydrolysis of CH3(CH2)6(CH3)2CSiCl3 (3) lead to the selective formation of the corresponding disiloxane tetrols [CH3(CH2) n (CH3)2CSi(OH)2]2O (2b-g; n = 1-6) in good yields. The TBAF-driven condensation reactions of the silanetriols CH3(CH2) n (CH3)2CSi(OH)3 (1a-c; n = 0-2) as well as
