Facile Synthesis of Unsymmetrical Trialkoxysilanols: (RO)2(R′O)SiOH

Trialkoxysilanols, (RO)3SiOH, are useful as ligands in transition-metal complexes because they provide models for silica-supported metal sites or precursors for the thermolytic precursor approach. However, their synthesis is mostly limited to symmetrical ones, where all RO ligands are the same. However, unsymmetrically substituted trialkoxysilanols could offer significant advantages over their symmetrical counterparts by facilitating crystallization of complexes, lowering crystallographic disorder, changing the thermal properties of the complexes made, and making the addition of pendant functional groups possible. Herein, a simple, general synthetic procedure yielding unsymmetrical trialkoxysilanols (RO)2(R′O)SiOH is presented using imidazole as a promoter.

Direct alkoxysilylation of alkoxysilanes for the synthesis of explicit alkoxysiloxane oligomers

Direct alkoxysilylation, which is a powerful tool to provide explicit alkoxysiloxanes, is developed and its versatility is investigated. Siloxane pentamers Si[OSiR1(OMe)2]4 having various functional groups (R1 = methyl, vinyl, phenyl, chloropropyl and n-butyl groups) were successfully obtained by direct alkoxysilylation of Si(OR)4 (R = t-Bu, CHPh2). Thus, the versatility of the reaction is confirmed on organic functional groups R1. Functional group tolerance of the reaction is discussed on the basis of electronegativity of the R1 groups. Alkoxysilylation of Si(Ot-Bu)2(OMe) 2 and Si(Ot-Bu)(OMe)3 selectively gives trimer (MeO) 2Si[OSiMe(OMe)2]2 and dimer (MeO) 3SiOSiMe(OMe)2, respectively. Thus, the feasibility on siloxane structure is also confirmed. Various siloxane compounds are synthesized by this newly developed reaction for the first time.
