Nitroalken

Nitroalken yoki nitro olefin, uning tarkibiy qismlari, alken va nitroguruhlarning funksionalligini birlashtirgan funktsional guruh boʻlib, alkenlarni faollashtirish orqali oʻzining kimyoviy xususiyatlarini namoyon qiladi va funktsional guruhni Maykl reaktsiyasi yoki Diels-Alder qo'shimchalari kabi maxsus reaktsiyalarda foydali qiladi.
