受各种钯源在咪唑基离子液体中形成纳米颗粒的倾向性的启发,我们现在报道带有十六烷基链和桥连间苯三甲部分的三咪唑盐是有效的钯纳米颗粒稳定剂,是通过钯的Chaudret型氢化有效制备的。双(二亚苄基丙酮)钯(0)。钯纳米粒子已经以纯净形式分离出来,其特征为1H核磁共振,透射电子显微镜,电子衍射和动态光散射。在钯含量为0.2%的情况下,新材料在铃木交叉偶联中被证明是有效的。因此,使用碘化三咪唑鎓钯材料,已从芳基溴化物和一些活化的氯化物开始制备了一系列联芳基产品。这种可能性,这催化活性可能是由于钯n中形成-杂环卡宾已通过固态寻址13 C NMR,并且其中所述酸性2-H用甲基取代的咪唑鎓类似物的合成。

Indenyl compound of formula (1)
wherein:
M is a transition metal from the lanthanides or from group 3, 4, 5 or 6 of the Periodic System of Elements,
Q is an anionic ligand to M,
k is the number of Q groups,
R is a bridging group
and Z and X are substituents, wherein R contains at least one sp2-hybridized carbon atom that is bonded to the indenyl group at the 2-position with the exclusion of Ti(deshydronorbiphenacene) dichloride.
Novel compounds of the formula ##STR1## are disclosed in which R.sup.1 is a phenyl, phenoxy, phenylthio, benzyl or heterocyclic radical which may be substituted, and R.sup.2 is hydrogen, a substituted-vinylcyclopropanecarbonyl group, a tetramethylcyclopropanecarbonyl group, or a 1-(substituted-phenyl)-2-methylpropylcarbonyl group. The compounds wherein R.sup.2 is other than hydrogen are insecticides.
Insecticidal 4-phenyl-2-indanyl 1R,cis-3-(2-halo-3,3,3-trifluoro-1-propenyl)-2,2-dimethylcyclopropanecarbo xylates having a racemic or optically active indanyl moiety, methods of preparation and use, and efficacy data against representative insect species are disclosed and exemplified.
