Next the fibres arepre-treated with alkaline to activate the hydroxyl group of cellulose and lignin in fibre and then it is suspended in 10% NaOH and benzoyl chloride
solution for 20 minutes.
3-O-Benzoyl-1,2:5,6-di-O-isopropylidene-[alpha]-D-gluco1,4-furanose (3): Benzoylation of the bisacetone Dglucose 2 (0.5 g, 1.92 mmol) with benzoyl chloride
(0.297 g, 2.113 mmol) gave 3-O-benzoate 3 (0.644 g, 92%) as a colorless solid, mp 86-88[degrees]C.
Figure 13 shows the scheme of the reaction of the BF with benzoyl chloride
Using the previous examples of chloroacetaldehyde dimethyl acetal, 97%; tetramethylammonium perchlorate; benzyl chloride; and benzoyl chloride
, these are, respectively, categories UN1993, UN1479, UN1738 and UN1736.
Acryloyl chloride (ACl) was prepared by reacting with benzoyl chloride
by following the procedure of Stampel et al.
Cannon also includes forms like benzonitrile and benzoyl chloride
as borrowings from Arabic, since the element benzo- has an Arabic origin.
-- Six 2-(2-pyridyl) cycloalkanones were synthesized by the condensation of morpholine enamine of the appropriate cycloalkanone with pyridine-1-oxide in the presence of benzoyl chloride
. Cyclopentanone, cyclohexanone, cyclopheptanone, cyclooctanone, cyclodecanone, and cyclododecanone were utilized.
Synthetic thiourea derivatives (1-5) of bromophenyl linked with amino acid were prepared by the reaction of benzoyl chloride
, potassium isothiocyanate and the corresponding amino acids.
(8.46 gm; 0.06 mol), dioxane (6 ml), Ethyl-2-(2,3-dichloroanilido) ethanoate (16.5 gm; 0.06 mol) and Triethylamine (6.06 gm; 0.06 mol) were placed in a round bottomed flask carrying reflux condensor having calcium chloride guard tube.
2-phenyl-4H-1,3-benzoxazin-4-ones (2a): To a stirred solution of anthranillic acid (0.01 M) (1) in pyridine (60 mL), benzoyl chloride
(0.01 M) was added dropwise, maintaining the temperature near 8[degrees]C for 1 h.
The polymer was synthesized by using Friedel-Crafts acylation of polystyrene with benzoyl chloride
, and was characterized by different instrumentations.
The iminium ion doesn't need to be preformed: the addition of benzoyl chloride
to the reaction mixture is sufficient to activate a variety of imines toward Pd-catalyzed coupling reactions with vinyl stannanes.
