2 General information Unless otherwise mentioned, all materials were commercially available and used without further purification. All the procedures were completed under the ambient air. 1 H NMR, 13 C NMR and 19 F NMR spectra were recorded at 400 (or 600) MHz, 101 (or 151) MHz or 376 MHz, respectively on a Bruker DPX instrument using Me 4 Si as an internal standard. Chemical shift multiplicities are represented as follows: (s = singlet, d = doublet, t = triplet, q = quadruple,p = quintuple, m = multiplet, td = tripletdoublet, dt = doublet triplet,dd = double doublet, dq = doublet quadruple). Melting points were measured on a WC-1 instrument and uncorrected. New compounds for HRMS were tested on a Waters Q-Tof Micro MS/MS System ESI spectrometer. All the naphthylamine substrates were synthesized according to literature procedures [1,2].[D 1 ]-1a was prepared according to the literature [3]. Experimental section 1.
