本文用烯丙基、丁烯-2-基环戊二烯基钠与IVB族金属氯化物反应,合成了新的双(烯丙基环戊二烯基)和双(丁烯-2-基环戊二烯基)二氯化钛、锆、铪.利用卤素交换或与芳基锂、硫氰酸钾、硫化氢反应制得双(烯基环戊二烯基)二卤、二芳基、二硫氰基和二巯基金属衍生物.考察了双(烯丙基环戊二烯基)二卤化钛、锆和铪中烯丙基与卤化氢、卤素的加成反应;与HX的加成反应均按马可尼可夫规则进行,加成反应活性是HI>HBr>HCl. 文中还研究了双(2-溴丙基环戊二烯基)金属衍生物中C—Br的反应活性,它们与硫氰酸钾、五氯苯酚钠和六次甲基四胺反应得到2-硫氰基、2-五氯苯氧基和2-氨基丙基环戊二烯基金属衍生物。
In this paper, allyl, buten-2-ylcyclopentadienyl sodium and Group IVB metal chloride were reacted to synthesize new bis (allylcyclopentadienyl) and bis (buten-2-yl Cyclopentadienyl) titanium dichloride, zirconium, hafnium Bis (alkenylcyclopentadienyl) dihalide is produced by the halogen exchange or with aryl lithium, potassium thiocyanate, hydrogen sulfide , Dithiocyanato and dimercapto metal derivatives were investigated.The addition reaction of allyl with hydrogen halide and halogen in bis (allylcyclopentadienyl) titanium dihalide, zirconium and hafnium The reaction was carried out according to the Markovnikov rule, and the addition reaction activity was HI> HBr> HCl. The reactivity of C-Br in bis (2-bromopropylcyclopentadienyl) metal derivatives was also studied , Which are reacted with potassium thiocyanate, sodium pentachlorophenate and hexamethylenetetramine to give 2-thiocyanato, 2-pentachlorophenoxy and 2-aminopropylcyclopentadienyl metal derivatives.
