A scandium(iii) trifluoromethanesulfonate-catalyzed O-metalation of silanols with 2-methylallylsilanes and 2-methylallylgermanes leading to siloxane or germasiloxane bond formation under mild conditions with evolution of isobutylene is described.

The direct trimethylsilylation reaction of olivine has yielded partial trimethylsilyl derivatives of ortho- and di-silicates whose unsilylated silanol groups have been esterified with the alcohol used as the organic solvent in the trimethylsilylating reagent.Gas chromatographic-mass spectroscopic measurements indicate the presence of the tri-, di-, and mono-alkyl-substituted trimethylsilyl derivatives of monosilicic acid in addition to the fully silylated monomeric derivative .Dimeric derivatives have also been detected which contain both the completely trimethylsilylated derivative and alcohol-esterified derivatives .The ratio of the esterified products varies with the volume of alcohol or water in the silylating reagent as well as the reaction time.
