Product Details of 36620-11-8. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate, is researched, Molecular C14H8BF4Rh, CAS is 36620-11-8, about Azine-N-oxides as effective controlling groups for Rh-catalyzed intermolecular alkyne hydroacylation.
Azine N-oxide substituted aldehydes are used as highly effective substrates with good reactivity for intermol. hydroacylation of alkynes. Employing a Rh(I)-catalyst, a mild and scalable aldehyde C-H activation, that permits the coupling with unactivated terminal alkynes was achieved in good yields and with high regioselectivities (up to >20 : 1 l:b). Both substrates can tolerate a broad variety of functional groups. The reaction can also be applied to diazine aldehydes that contain a free N-lone pair. Conversion of the hydroacylation products to the corresponding azine, through a one-pot hydroacylation/deoxygenation sequence was also demonstrated. A one-pot hydroacylation/cyclization, using N-Boc propargylamine, addnl. leads to the synthesis of a bidentate pyrrolyl ligand.
