A series of methylene-bridged bis(triarylboranes) has been synthesized via two complementary routes using metal-free catalytic Si/B exchange condensation under mild conditions. The title compounds comprise two borane moieties that show effective inte

A series of bifuran-bridged bis(triarylboranes) have been synthesized via classical metathesis or catalytic silicon/boron exchange reactions, respectively. The products obtained are strongly luminescent, with quantum yields up to 85%, and reversibly

The potential of our metal-free B–C coupling method using catalytic Si/B exchange condensation is demonstrated by the synthesis of a series of monodisperse (het)arylborane oligomers with four (het)arene moieties and three boron centers (i.e., ‘tr

The synthesis of borazine-based hybrid cyclomatrix polymers has been studied under various conditions. Crosslinked polymers obtained via a novel silicon/boron exchange precipitation polycondensation approach form hybrid cyclomatrix microspheres with

The reaction of n-C8 H17 B[N(Me)SiMe3 ]2 (1) with n-C8 H17 BCl2 (2 a) yielded, instead of a linear poly(iminoborane), the aminoborane n-C8 H17 B(Cl)N(Me)SiMe3 (4) and after cyclotrimerization the borazine cyclo-(n-C8 H17 BNMe)3 (6). Side reactions th
