Abstract
Two new oxygen-chelated ruthenium-indenylidene complexes, 1 and 2, with activity for ring-opening metathesis polymerization (ROMP), have been synthesized from simple ruthenium complexes, such as [Ru(PPh3)3Cl2], [Ru(p-cymene)Cl2]2 or [Ru(p-cymene)(PCy3)Cl2 and propargyl alcohol in one step. Complexes 1 and 2 were evaluated by the ROMP of endo-dicyclopentadiene to form polydicyclopentadiene.
Tóm tắt
Hai phức hợp mới của chelate-oxygen ruthenium-indenylidene, 1 và 2, có hoạt tính trong phản ứng trùng hợp mở vòng, được tổng hợp từ các chất nền đơn giản của ruthenium: [Ru(PPh3)3Cl2], [Ru(p-cymene)Cl2]2 hoặc [Ru(p-cymene)(PCy3)Cl2 và một rượu propargylic chỉ trong một bước. Cả hai phức hợp 1 và 2 được đánh giá hoạt tính qua phản ứng trùng hợp mở vòng của endo-dicyclopentadiene tạo thành polydicyclopentadien.
