<p>The invention relates to alkylborane complexes with aromatic amines of the formula: -
<Chemistry id="chema01" num="0001"><Image id="ia01" he="17" wi="61" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>in which R<Sup>1</Sup> and R<Sup>2</Sup> are the same or different (1-4C)-alkyl radicals, or together with the adjacent nitrogen atom are morpholino, piperidino or pyrrolidino radicals; R<Sup>3</Sup> and R<Sup>4</Sup> are independently selected from hydrogen, (1-4C)-alkyl, (1-4C)-alkoxy, di-(1-4C)-alkylamino, morpholino, piperidino and pyrrolidino; thexyl stands for 1,1,2-trimethylpropyl; and n is the integer 1 when R<Sup>3</Sup> and R<Sup>4</Sup> are other than nitrogen containing radicals, or the integer 1 or 2 when one of R<Sup>3</Sup> and R<Sup>4</Sup> is a nitrogen containing radical, or the integer 1, 2 or 3 when both R<Sup>3</Sup> and R<Sup>4</Sup> are nitrogen containing radicals.</p><p>The complexes are more stable than thexylborane tetrahydrofuran complex, but are sufficiently reactive to be valuable as hydroborating and reducing agents.</p><p>The invention also provides solutions of the complexes of formula I in organic solvents for convenient storage or subsequent synthetic use, and a process for manufacturing said complexes.</p><p>A particularly convenient complex of the invention is thexylborane N,N-diethylaniline complex.</p> |
