Hitherto unknown germaacid chloride (1), germaester (2), and Ngermaacyl pyrrole (3) compounds are stabilised as Lewis acid complexes. Reactivity studies on them yielded compounds such as germaynone (4) and germaacyl thioester (10).

Bond Strengths

Dimethylsulfane-borane, (CH3)2SBH3, reacts with X2, HX and BX3 to give (CH3)2SBH2X and (CH3)2SBHX2 (X = Br, I). Although BI3 is the strongest Lewis-acid amongst the boron compounds, it does not form (CH3)2SBI3 but (CH3)2SBHI2 and B2H6, when it is mixed with (CH3)2SBH3. 1H—NMR results indicate an increase in the donor-acceptor bond strengths with decreasing n in the series (CH3)2SBHnX3-n.

High Yields

A method for efficient and mild synthesis of diarylmethylamine scaffold, via Lewis acid catalyzed Friedel–Crafts reaction of donor­–acceptor aziridines with N,N-dialkylanilines to afford a biologically important diarylmethylamine derivatives in high yields (up to 88%), is presented. This reaction is suitable for the synthesis of various diarylmethylamine derivatives and has a broad scope for electron-rich arenes, including dimethoxybenzene.
