Abstract
A copper-catalyzed trifluoromethylation–cyclization of olefinic carbonyls was developed. With this method, a variety of 2,3-dihydrofuran and 3,4-dihydropyran derivatives containing a CF3 group were selectively obtained in moderate to good yields.

Abstract
Cyclobutanetetrone, (CO)4, has a triplet ground state. Here we predict, based on electronic structure calculations, that the B2N2O4 molecule also has a triplet ground state and is therefore paramagnetic; the structure is an analogue of (CO)4 in which the carbon ring is replaced by a (BN)2 ring. Similar to (CO)4, the triplet ground-state structure of B2N2O4 is also thermodynamically unstable. Besides analysis of the molecular orbitals, we found that the partial atomic charges are good indicators for predicting magnetic ground states.
