Diastereoselective Remote C-H Activation by Hydroboration.
Hydroboration of tetrasubstituted or trisubstituted alkenes with borane and subsequent thermolysis allows remote diastereoselective C-H activation of neighboring aryl rings. The mechanism of this remote activation has been studied and extend...

Substituent Dependent Cyclization Reactions of 1,1'-Bis(alkynyl)ferrocenes with the (C6F5)BH2 . SMe2 Hydroboration Reagent
The reaction of 1,1'-bis(tert-butylethynyl)ferrocene (4 a) with the (C6F5)BH2 . SMe2 reagent results in two-fold hydroboration to give the boron containing [3]ferrocenophane 5. It reacts with xylylisocyanide by insertion into the boron-carbo...

Intramolecular Pericyclic Re-hydroboration via Six-membered Transition State: Synthesis of Fused Borolo[3,2-b]siloles
We experimentally demonstrate a new type of the intramolecular reaction between non-activated alkyne units and the dialkylboryl group (9-BBN), which was previously only hypothesized and studied on a calculational level. The reaction described here ca...
