Self-immolative systems for the disclosure of reactive electrophilic alkylating agents.

In this paper we report the design, synthesis and assessment of the first examples of self-immolative systems triggered by non-acidic electrophilic agents such as methyl, allyl or benzylic halides. These systems provide a visual colorimetric disclosure response upon exposure to these electrophilic reagents undermild, basic conditions without the need for the use of analytical instrumentation.
