The ansa-aminohydroborane 1-NMe2-2-(BH2)C6H4crystallizes in an unprecedented type of dimer containing a B?H bond activated by one FLP moiety. Upon mild heating and without the use of any catalyst, this molecule liberates one equivalent of hydrogen to generate a diborane molecule. The synthesis and structural characterization of these new compounds, as well as the kinetic monitoring of the reaction and the DFT investigation of its mechanism, are reported.

The FLP species 1-BR2-2-NMe2-C6H4 (R = 2,4,6-Me3C6H21, 2,4,5-Me3C6H22) reacts with H2 in sequential hydrogen activation and protodeborylation reactions to give (1-BH2-2-NMe2-C6H4)23. While 1 reacts with H2/CO2 to give formyl, acetal and methoxy-derivatives, 2 reacts with H2/CO2 to give C6H4(NMe2)(B(2,4,5-Me3C6H2)O)2CH24. The mechanism of CO2 reduction is considered.

Phenanthridines and azocines fused to two benzene rings or one benzene and one pyridazinone ring, which are otherwise difficult to access, were prepared via two new extensions of the tert-amino effect. The synthetic pathway includes three steps: i) Suzuki reaction of an ortho-functionalized phenylboronic acid with ortho-disubstituted benzenes or pyridazinones; ii) the Knoevenagel condensation reaction of the biaryl aldehydes formed with active methylene compounds to obtain vinyl derivatives or, through their cyclization, phenanthridines via a tert-amino effect; and iii) thermal isomerization of vinyl or phenanthridinium compounds to fused azocines via another type of tert-amino effect.

Synthesis and properties of fluorescent organoboranes: Triarylmethane-type dyes
Albrecht, Karsten,Kaiser, Volker,Boese, Roland,Adams, Joerg,Kaufmann, Dieter E.
, p. 2153 - 2157 (2007/10/03)
The syntheses and photochemical properties of the novel aminoaryldiarylboranes, 4, which are isoelectronic with triarylmethane dyes, and also pyrrolyl-8, and indolyl-diarylboranes 11, are described. The fluorescence spectra are strongly dependent on the s
