Synthesis and photoinitiation activity of radical polymeric photoinitiators bearing side-chain camphorquinone moieties

“…Following a procedure reported for similar derivatives, [8] pivaloyl chloride (71 mmol) was added under stirring to N,N-dimethylethanolamine (71 mmol) in dry benzene (20 ml) at a dropping rate sufficient to maintain the reaction temperature around 40-50 8C. The mixture was then heated at reflux for 12 h, cooled and treated with cold Na 2 CO 3 (80 mmol) in water (5 ml).…”

Polymeric photoinitiators based on side‐chain benzoin methyl ether and tertiary amine moieties for fast UV curable coatings

“…64 "C and 90 "C/12 mbar, respectively). DEPA was synthesized as described elsewhere [13] starting from 3-(N,N-diethylamino) propan-1-01 and acryloyl chloride. 'H-NMR (CDCl,): 6 (ppm from TMS) 6.5-5.8 (m, 3H, CH-H); 4.2 (t, 2H, OCH,); 2.6-2.4 (m, 6H, N-CHJ; 1.8 (q, 2H, C-CH,); 1.05 (t, 6H, CH,).…”

“…FT-IR (liquid film) (cm-'): 3087-3025 (vCH aromatic rings); 2975-2830 (vCH, aliphatic); 1738 (vcs ester group); 1676 (vc4 ketone group); 1598 (vc4 aromatic rings); 1470 (BCH2); 1388 and 1362 ( & , , geminal methyl groups in isopropyl moiety); 1130 ( Y , ,~~~, methyl ether); 760 and 690 (dCH monosubstituted aromatic rings). DMEI was prepared from 2-(N,N-dimethy1amino)ethanol and isobutyryl chloride as reported for DAPA [13]. 'H-NMR (CDClJ: 6 (ppm from TMS…”

Tetraphenylboroxinate(1-) salts of monoborate cations: Synthesis and single-crystal X-ray structures of [Ph2B{OCH2CH2N(Me)(CH2)n}2][Ph4B3O3] (n=4, 5)

“…In order to attempt the preparation by this route of new 2-hydroxyethyl substituted non-metal cation salts of [Ph 4 B 3 O 3 ] À it was first necessary to prepare solutions of the desired non-metal cation hydroxides. The iodide salts [1-(2-hydroxyethyl)-1-Me-pyr-]I, were prepared by literature methods from the free bases using MeI, and their purity confirmed by NMR and/or mpt data[10,11]. The iodide salts were converted to methanolic solutions of their corresponding hydroxide salts [(HOCH 2 CH 2 )N(Me)0022-328X/$ -see front matter Ó 2009 Elsevier B.V. All rights reserved.…”
