摘要： (KCn)2TiCl2的乙酰丙酮体系在水相中与硫氰酸钾、吡咯烷基二硫代氨基甲酸钠、取代苯甲酸钠等反应,合成得到相应的(单)双环戊二烯基(或甲基环戊二烯基)钛衍生物。双环戊二烯基二水杨酸钛单晶的结构分析表明,水杨酸作为单齿配体通过梭基氧原子与钛键联。

Abstract: The (KCn)2TiCl2(R=H, Me )-acetylacetone system reacts with potassium thiocyanate, sodium thiocarbamate or sodium 2- substituted benzoates in aqueous medium, giving (RCp)2Ti(SCN)2,(RCp)Ti(S2CNR2)3 and (RCp)2Ti(O2C(2-X)C6H4)2 respectly,(X=OH,CI,NH2) except for bis(methylcyclopentadienyl )salicylatotitanium. The structure of titanocene bis(salicylate ) single crystal was determined by X-ray diffraction. The compound crystallizes in orthorhombic space group Pccn with a=1. 3538(3)nm,b=1. 4273(5)nm,c=2.1506(7)nm, z=8,R=0.042 and Rw=0.039。

Key words: cyclopentadienyl, titanium compound, aquachemistry, crystal structure
