ChemInform Abstract: Reactions of Steroidal Nitroolefins with Ethanethiol and BF3‐Etherate CatalyststeroidsIn the presence of BF 3 ·Et 2 O, 6-nitrocholest-5-ene (Ia), its 3β-acetoxy derivative (Ib) and its 3β-chloro derivative (Ic) undergo smooth reaction with EtSH (II) to afford ...
Reactions were conducted on a 0.2 mmol scale with 10.0 equivalents of BF3·Et2O in DCE (8.0 mL) at −25 °C for 48 h. The absolute configuration of4bwas assigned by X-ray crystallography (structure shown), and the configuration of all other products was assigned by analogy....

Reactions of several arylsulfenamides were studied, with various cyclic and polycyclic alkenes, in the presence of boron trifluoride etherate. Depending on the structures of the sulfenamide and the alkene, the reaction proceeds to give either products of nitrogen fragment bonding or the relevant fluor...

The appearance potentials of three-component aggregates and of boron trifluoride dimethyl etherate clusters have been measured by using monochromatized synchrotron radiation. Different fragmentation processes and chemical intra-cluster reactions have been observed. [BF (O(CH ) )] is unstable but stable...
