Synthesis of functionalized 1-trimethylsiloxy-substituted O-trimethylsilyl alkylphosphonites and their derivatives

Nucleophilic addition of trimethylsilyl esters of tricoordinate organophosphorus acids to various functionalized aldehydes with vinyl, aryl, and heterocyclic fragments is proposed as a convenient method for the synthesis of new 1-trimethylsiloxysubstituted alkylphosphonites and their derivatives at mild conditions. Also the new functionalized derivatives of these phosphonites, including amino groups as well as certain properties of these compounds as important precursors of new functionalized 1-hydroxyalkylorganophosphorus acids, are presented.

29Si and 13C NMR Spectra of 4-Substituted 2-Methoxytrimethylsiloxybenzenes. Factors Determining the Chemical Shifts in Models of Lignin Constituents

29Si and 13C NMR chemical shifts are reported for a series of twenty 4-substituted 2-methoxytrimethylsiloxybenzenes; the set of substituents incorporates a basic set of ten substituents differing in their relative polar and resonance effects and ten other

UNERWARTETE REAKTIONSPRODUKTE VON N-METHYL-N-TRIMETHYLSILYLTRIFLUORACETAMID (MSTFA) MIT ALDEHYDEN

Aldehydes react with MSTFA (N-methyl-N-trimethylsilyl-trifluoroacetamide) to give E/Z-silylenolethers and surprisingly addition products of the reagent to the carbonyl group.The mass spectra of the MSTFA/aliphatic aldehyde adducts are dominated by a key fragment of m/z 228 formed by elimination of the alkyl part.With MSTFA/aromatic aldehyde adducts this fragmentation is replaced by M-H and M-CH3N.8COCF3 (M-126 amu) ions.
