تفاعل بيشامب

تفاعل بيشامب (Bechamp reaction) في التخليق العضوي، يُستخدم تفاعل بيشامب لإنتاج أحماض الزرنيخون من الحلقات العطرية النشطة مثل الأنيلين.[1][2][3][4] وقد تم وصفه لأول مرة بواسطة «بيشامب» عام 1863. هذا التفاعل هو استبدال عطري الكتروفيلي ، وذلك باستخدام حمض الزرنيخ كمادة متفاعلة.

أحد الأمثلة الهامة لحمض الزرنيخون هو الروكسارسون . وهو عبارة عن 4- هيدروكسي-3- نيترو بنزين حمض الزرنيخون. ويُظهر تأثير مضاد لطفيليات الأكريات ويعزز النمو في الحيوانات.[5]
