ثنائي الترابط المائي

ثنائي الترابط المائي Hydrodimerization( في الكيمياء العضوية) هو عبارة عن تفاعل عضوي يجمع بين ألكينين لإنتاج هيدروكربون متماثل symmetrical hydrocarbon . يتم التفاعل غالبًا بطريقة كهروكيميائية ؛ وفي هذه الحالة يسمى ثنائي الترابط الكهربي electrodimerization . يمكن أيضًا حث التفاعل باستخدام ثنائي يوديد السماريوم ، وهو مادة اختزال ذات إلكترون واحد .

التحلل المائي هو أساس تخليق مونسانتو أديبونيتريل : ^[1]

2CH₂=CHCN + 2 e⁻ + 2 H⁺ → NCCH₂CH₂CH₂CH₂CN

ينطبق التفاعل على عدد من الألكينات المحبة للكهرباء ( مستقبلات مايكل ). ^[2] ^[3]
