2- bromotoluenes

Referring to the numerical example following Eq. 11-18, what would be the surface tension of a liquid of density 1.423 g/crc (2-bromotoluene), the rest of the data being the same ... 

For the preparation of w-bromotoluene, the following sequence of reactions from p-toluidine may be used ... 

An example of this is given in Section IV.63—the conversion of 3-bromo-4-aminotoluene into m-bromotoluene. Another application is to the preparation of. iM.-tribromobenzene (Section IV,72) ... 

Prepare a solution of p-tolyldiazonium chloride from 53 -5 g. of p-tolui-dine using the proportions and experimental conditions given under p-Chlorotoluene (Section IV,61). Add the diazonium chloride solution to the boiling cuprous bromide solution, and proceed as in Method 1. The yield of pure, colourless p-bromotoluene, b.p, 182-184° (mainly 183°), is 40 g. m.p. 26°,... 

For initial experience in the uae of Uthium, the preparation of either p-toluic acid or of a-napbtboic acid mcay be undertaken. For the former, p-bromotoluene is converted into the lithium derivative and the latter carbonated with soUd carbon dioxide ... 

By the reaction of bromotoluene with ethylene under pressure, p-methylsty-rene and stilbene (45) are obtained[44,45]. A polymer 47 is obtained by the reaction of >-bromostyrene (46) with ethylene. The reaction has been applied to polymer synthesis[46]. One example is the reaction of 1,4-divinylbenzcne (48) with 9,10-dibromoanthracene to give the oligo(arylenevinylene)s 49[47]. 

Partial rate factors may be used to estimate product distributions in disubstituted benzene derivatives The reactivity of a particular position in o bromotoluene for example is given by the product of the partial rate factors for the corresponding position in toluene and bromobenzene On the basis of the partial rate factor data given here for Fnedel-Crafts acylation predict the major product of the reaction of o bromotoluene with acetyl chlonde and aluminum chloride... 

Three regioisomers (o m and p methylamline) were formed from m bromotoluene CH3 CH3 CH3 CH3... 

The hydrolysis of p bromotoluene with aqueous sodium hydroxide at 300°C yields m methylphenol and p methylphenol in a 5 4 ratio What is the meta—para ratio for the same reac tion carried out on p chlorotoluene" ...
