Chlonde

Coupling of 2-diethyiamino-4-methvlselenazole with phenyldiazonium chlonde gives the corresponding 5-phenylazo compound [orange granules, m.p. 101°C (26)]. [Pg.246]

Methyl 2 propanol Hydrogen chlonde ten butyl alcohol)... [Pg.152]

Because tertiary alcohols are so readily converted to chlorides with hydrogen chlo nde thionyl chlonde is used mainly to prepare pnmary and secondary alkyl chlondes Reactions with thionyl chlonde are normally carried out m the presence of potassium carbonate or the weak organic base pyndme...

Cyclopropyl chlonde has been prepared by the free radical chlorination of cyclopropane Wnte a stepwise mechanism for this reaction... [Pg.186]

If the temperature is not kept below 25°C dunng the reaction of primary alcohols with p toluenesulfonyl chloride in pyndine it is sometimes observed that the isolated product is not the desired alkyl p toluenesulfonate but is instead the corresponding alkyl chlonde Suggest a mech anistic explanation for this observation... [Pg.362]

A substantial body of evidence indicates that allylic carbocations are more stable than simple alkyl cations For example the rate of solvolysis of a chlonde that is both tertiary and allylic is much faster than that of a typical tertiary alkyl chloride... [Pg.391]

Allyl chlonde is quite reactive toward nucleophilic substitutions especially those that proceed by the 8 2 mechanism and is used as a starting material m the synthesis of a variety of drugs and agricultural and industrial chemicals... [Pg.397]

Chloro 1 3 butadiene (chloroprene) is the monomer from which the elastomer neoprene IS prepared 2 Chloro 1 3 butadiene is the thermodynamically controlled product formed by addi tion of hydrogen chloride to vinylacetylene (H2C=CHC=CH) The principal product under conditions of kinetic control is the allenic chlonde 4 chloro 1 2 butadiene Suggest a mechanism to account for the formation of each product... [Pg.420]

Alkyl halides by themselves are insufficiently electrophilic to react with benzene Aluminum chloride serves as a Lewis acid catalyst to enhance the electrophihcity of the alkylating agent With tertiary and secondary alkyl halides the addition of aluminum chlonde leads to the formation of carbocations which then attack the aromatic ring...
