Radicals 2 and 3 were generated by PbO₂ oxidation of N-(arylthio)-2-tert-butyl-4,6-diarylanilines and N-(arylthio)-4-tert-butyl-2,6-diarylanilines, and seven radicals were isolated as the pure radical crystals. The X-ray crystallog. structures of N-[(4-nitrophenyl)thio]-6-tert-butyl-2,4-diphenylphenylaminyl and N-[(4-nitrophenyl)thio]-4-tert-butyl-2,6-diphenylphenylaminyl radicals were determined The magnetic susceptibility measurements for the isolated radicals were carried out in the temperature range 1.8-300 K with a SQUID magnetometer. Among the four radicals studied the two were analyzed by an alternating one-dimensional Heisenberg model with J₁/k = -1.8 (α = 0.86) and -18.2 K (α = 0.16), and the other two were analyzed by a one-dimensional regular Heisenberg model with J₁/k = -30.8 K or a singlet-triplet dimer model with J₁/k = -45.2 K.

Ploypradith, Poonsakdi published the artcileUtility of Polymer-Supported Reagents in the Total Synthesis of Lamellarins, Related Products of bromides-buliding-blocks, the publication is Journal of Organic Chemistry (2005), 70(13), 5119-5125, database is CAplus and MEDLINE.

Four solid-supported reagents have been utilized in the multistep synthesis of lamellarins. The use of Amberlyst A-26 Br₃^– and polymer bound pyridine hydrobromide perbromide (PVPHP) for keto α-bromination of the less studied ortho-substituted acetophenone derivatives selectively furnished the corresponding monobromination products (phenacyl bromide derivatives), which were used directly in condensation reactions with benzyldihydroisoquinoline mediated by Amberlyst A-26 NaCO₃^–. The 2H-pyrrole carbonates subsequently underwent intramol. Friedel-Crafts transacylation followed by lactonization to provide the lamellarin skeleton (e.g. I). Alternatively, Amberlyst A-26 NaCO₃^– effectively served as base in condensation reaction of benzyldihydroisoquinoline with α-nitrocinnamate derivatives to provide the corresponding 2-ethoxycarbonyl pyrroles, which smoothly underwent O-debenzylation reaction followed by lactonization to furnish the lamellarin skeleton. The novel Amberlyst-15 mediated lactonization reactions effectively combined the otherwise two sep. steps into a single transformation.
