(1RS,2SR)-1,2,4,5,7-pentabromo-5-methoxyindane

Tutar, Ahmet; Çakmak, Ömer (BLACKWELL MUNKSGAARD, 2005)

In the title compound, C10H7Br5O, prepared by bromination of 5- methoxyindane, all bond lengths and angles are in the usual ranges. However, the relatively wide range of Br - C - C angles [ 107.2 ( 5) - 117.0 ( 4)degrees] ...
Efficient and selective synthesis of quinoline derivatives

Çakmak, Ömer; Tutar, Ahmet (PERGAMON-ELSEVIER SCIENCE LTD, 2008)

The bromination reaction of 1,2,3,4-tetrahydroquinoline (7) was investigated by NBS and molecular bromine. One-pot synthesis is described for synthetically valuable 4,6,8-tribromoquinoline (3) and 6,8-dibromo-1,2,3,4-tet ...
Functionalisation of indene

Tutar, Ahmet; Çakmak, Ömer; Balci, Mustafa (SCIENCE REVIEWS LTD, 2006)

Dibromo- and tribromoindane were synthesised by bromination of indene. Treatment of dibromo- and tribromoindane with various silver salts (silver acetate, perchlorate, sulfate and nitrate) in different solvents opened up ...
Synthesis of new anthracene derivatives

Çakmak, Ömer; Tutar, Ahmet (AMER CHEMICAL SOC, 2006)

An efficient synthesis is described for hexabromoanthracenes 3 and 4 by direct brom nation of 9,10-dibromoanthrecene 2. Whereas base-induced elimination of hexabromide 3 with t-BuOK gave 2,3,9,10-tetrabromoanthracene 5, ...
