The easy preparation of N-alkyl N-trimethylsilyl alkoxymethylamines is described; these new reagents are very convenient to lead to unsymmetrical secondary amines from organometallic compounds.

Me3SiN(H)R (R = Et, Pri, But, or Ph) yields the amido complexes cpTi(Cl)2N(H)R, which react further by HCl abstraction to give the corresponding centrosymmetric binuclear imido complexes [cp(Cl)Ti]2(µ-RN)2; substitution of the chloride ligands by organic groups is possible with the imido complexes, as is reversible reduction to stable anionic complexes.
Die Addition der N-Alkyl-N′-(trimethylsilyl)carbodiimide 1 - 7 an die Halogenketene 9 - 11 verläft regioselektiv, wobei die in 3-Position halogenierten 1-Alkyl-4-[(trimethylsilyl)imino]-2-azetidinone 12 - 21 entstehen. Diese lassen sich leicht zu den halogenierten 1-Alkyl-4-imino-2-azetidinonen 22 - 31 entsilylieren. - Diphenylacetylchlorid liefert mit dem Carbodiimid 6 das Säureamid 32, und Bernsteinsäure-dichlorid

The simple or functional N-alkyl-N-trimethylsilylalkoxymethylamines are very convenient new reagents for the route to unsymmetricalsecondary functional amines from organometallic compounds (M Al, Mg, Zn) prepared from α-unsaturated halides, functional terminal alkynes or α-bromoesters (or amides).
