Tungsten coordination chemistry of 1,4-bisdiphenylphosphinobutadiyne — Synthesis of coordination macrocycles and factors controlling diyne cycloaddition作者：Jordan A Tsui、Timothy M Bolton、Brian T SterenbergDOI：10.1139/v08-123日期：2009.1.1
The 1:1 reaction of [W(CO)4(2-picoline)2] (1) with Ph2PCtriple bondC-Ctriple bondCPPh2 (2) led to [cis-W(CO)4]2(µ-Ph2PC4PPh2)2} (3), in which two bis(diphenylphosphino)butadiyne ligands bridge two tetracarbonyltungsten centres. Reaction of 1 with excess 2 led to [cis-W(CO)4(Ph2PC4PPh2-κ1-P)2] (4), in which two dangling bis-phosphines are coordinated to one metal centre, and reaction of 2 with two equivalents of 1 led to [W(2-picoline)(CO)4]2(µ-Ph2PC4PPh2)} (5), in which one ligand bridges two tungsten centres. Combination of 4 and 5 led to the trimeric complex [cis-W(CO)4]3(µ-Ph2PC4PPh2)3} (6), in which three tetracarbonyltungsten centres are bridged by three bisdiphenylphosphinobutadiyne ligands. The dimeric complex 3 showed no reactivity towards alkyne cycloaddition; however, the trimeric complex 6 undergoes cycloaddition at moderate temperatures to form [W(CO)4]3[µ3-C12(Ph2P)6]} (8), which contains a cyclododecatrienetriyene ring. Comparison of structural data for the template complexes 3 and 6, as well that of previously described platinum template complexes, suggests that alkyne cycloaddition reactions are favoured by proximity of the alkynyl carbons α to phosphorus in adjacent ligands.Key words: coordination chemistry, diyne, cycloaddition, templated reaction, tungsten.
W(CO)4(2-picoline)2] (1) 与 Ph2PCtriple bondC-Ctriple bondCPPh2 (2) 发生 1:1 反应，生成[顺式-W(CO)4]2(μ-Ph2PC4PPh2)2} (3)，其中两个双(二苯基膦)丁二炔配体连接两个四碳钨中心。1 与过量的 2 反应生成[顺式-W(CO)4(Ph2PC4PPh2-κ1-P)2](4)，其中两个悬垂双膦配位到一个金属中心；2 与两个当量的 1 反应生成[W(2-吡啶)(CO)4]2(μ-Ph2PC4PPh2)}(5)，其中一个配体桥接两个钨中心。4 和 5 的组合产生了三元复合物[顺式-W(CO)4]3(µ-Ph2PC4PPh2)3}（6），其中三个双二苯基膦丁二炔配体桥接了三个四碳基钨中心。二聚络合物 3 对炔烃环加成没有反应活性；但是，三聚络合物 6 在中等温度下会发生环加成反应，形成[W(CO)4]3[μ3-C12(Ph2P)6]} (8)，其中含有一个环十二碳三乙烯环。比较模板配合物 3 和 6 以及以前描述的铂模板配合物的结构数据表明，炔基碳原子 α 与相邻配体中的磷接近，有利于炔环化反应。 -
A Metal-Templated 4 + 2 Cycloaddition Reaction of an Alkyne and a Diyne To Form a 1,2-Aryne作者：Jordan A. Tsui、Brian T. SterenbergDOI：10.1021/om900578d日期：2009.9.14bis-phosphino diyne substrates to mixed platinum and tungsten metal templates results in a templated 4 + 2 alkyne−diyne cycloaddition reaction to form an aryne intermediate, which abstracts two H atoms to form an arene ring. The aryne intermediate can also be trapped via a Diels−Alder reaction with furan.
