Recently,we have reported the reaction of butadiene-and isoprene(tricarbonyl)iron,in which the olefin ligand is a straight chain or branched chain conjugated diene,with nucleo-phile aryllithium at low temperature and followed by subsequent alkylation with Et_3OBF_4to give a series of novel isomerized butadiene-and isoprene(dicarbonyl)[ethoxy(aryl)carbene]-iron complexes respectively.The structure of these complexes showed that the bondingmodes of central metal atom and olefin ligands are quite unique.Now we choose,as starting Recently, we have reported the reaction of butadiene-and isoprene (tricarbonyl) iron, in which the olefin ligand is a straight chain or branched chain conjugated diene, with nucleo-phile aryllithium at low temperature and followed by subsequent alkylation with Et_3OBF_4to give a series of novel isomerized butadiene-and isoprene (dicarbonyl) [ethoxy (aryl) carbene] -iron complexes respectively.

B655牛头刨床是设备利用率较高的设备。大修时,一般都要更换摇杆传动小齿轮,但经过几个修理周期后,大斜齿轮的齿面也会因长期使用而磨损研伤,造成公法线超差,产生机床噪音,
对校正大直径薄壁圆环,如果用铁锤来敲击是不容易校正的。为此,我们用两块较大的槽钢合拼在一起,再用四根大小一样的方钢(头部弯成圆形)焊在槽钢上,将两根 It is not easy
