Efficient green procedures for the preparation of novel tetraalkynyl-substituted phthalocyanines

(24-Сrown-8)-Linked Dimeric Phthalocyanines and Their Metal Complexes

“…Magnesium cation was chosen as template since it can be easily removed from the phthalocyanine producing metal-free ligand. The template cation can be introduced into the reaction mixture in two different ways: by application of magnesium alkoxide as nucleophile in the synthesis [58,59] or by addition of magnesium salt [60,61] to the reaction mixture. We have tested both approaches for preparation of the target dimeric phthalocyanines.…”

A simple and effective approach for catalytic reductive dechlorination of aromatic compounds

“…18 All the mono chlorinated aromatic compounds (CACs) used in this work: 1-Chloro-4-methylbenzene (98%), 1-Chloro-4-ethylbenzene (97%), 1-Chloro-4-propylbenzene (97%), 4-Chlorobiphenyl (95%), 1-Chloronaphthalene (85%) and 1-Chloroanthracene (95%) were purchased from Acros and Aldrich and used as received. The other reagents, such as organic solvents and bases were analytical grade.…”

“…The phthalonitrile derivative 1 was synthesized as reported in our previous work. 18 The phthalonitrile derivative 1 was irradiated in a microwave reactor at 370W for 10 min, in the presence of CoCl 2 to form the desired complex 2. The new cobalt phthalocyanine 2 was purified by column chromatography with aluminum oxide as an adsorbent.…”

“…The new cobalt phthalocyanine 2 was purified by column chromatography with aluminum oxide as an adsorbent. It was obtained in a yield of 67% and was characterized previously by spectral data (IR, UVVisible spectroscopy, mass spectral data and elemental analysis) [18].…”

Manganese phthalocyanine immobilized on silica gel: Efficient and recyclable catalyst for single-step oxidative esterification of aldehydes with alcohols

“…[37] with slight modification (Supplementary material). To prepare tetrakis-(2-methoxy-4-formylphenoxy)phthalocyaninato manganese(III) acetate [38], a mixture of manganese acetate (0.77 mmol, 0.206 g), 4-(2-methoxy-4-formylphenoxy)phthalonitrile (18.5 mmol, 5.14 g), N,N-dimethylaminoethanol (DMAE) (5 ml) and DBU (1 mL) were irradiated in microwave reactor at 370 W for 10 min. After cooling to room temperature the solution was poured into methanol/water (3:1) and centrifuged.…”
