[2 + 4] Cycloaddition reactions of dialkylaminobis(trifluoromethyl)boranes with 1,3-dienes, β-unsaturated carbonyl compounds and methyl methacrylate. Crystal structures of (CF3)2H2, R = Me and Et, and (CF3)2
摘要:
and characterized by multinuclearNMR spectroscopy and by mass spectrometry, and IR and Raman spectroscopy. The crystal structures of the compounds (CF3)2H2, R = Me and Et, and (CF3)2 have been determined by X-ray diffraction studies. They show that the BN and BCF3 bonds are somewhat longer than those in acyclic amine adducts of bis(trifluoromethyl)boranes. Furthermore, evidence is presented for steric
