In the case of an equimolar or 2/1 ratio of protected hydrazine and benzyl bromide, relatively poor yields ranging from 13% to 30% were obtained at room temperature.
A detailed study of mono-protected hydrazines using benzyl bromide was performed, and the most suitable conditions for these reactions were found.
Since MBT is a mono-functional nucleophile, it will react with the benzyl bromide sites forming nonreactive mercaptobenzothiazyl benzyl sulfides.
The reaction involves the hydrolysis of the bunte salt followed by the nucleophilic reaction of the bis(thiolate) with the benzyl bromides (figure 16).
Benzyl bromide and other halogenated reagents were purchased from several commercial sources.
The sodium-metallated PMIA was reacted with benzyl bromide first.

The effect of benzyl bromide (BzBr) groups in BIMS on adhesion to nylon and IR will be discussed in this work.
To test the first possibility, we react benzyl bromide (98%; used as received from Aldrich) with [Epsilon]-caprolactam (99+%; used as received from Aldrich):

The very reactivity nature of the benzyl bromide
functionality permits curing to proceed by a variety of paths.
H NMR and IR analysis of the polymer showed the complete conversion of the benzyl bromide
to benzyl ester.
