This Ph.D. thesis describes further studies on theformation of fluorinated phosphorus ylide-anions resultingfrom organometallics and their reactions, stereochemistry andapplications in organic synthesis. We found that inverse stereochemical results wereobserved in the reaction of the fluorinated ylide-anions withvarious proton donors.

本博士论文进一步研究了用有机金属试剂对含氟膦叶立德的亲核加成导致的叶立德阴离子的反应性、立体选择性及其在有机合成中的应用：首次发现含氟叶立德阴离子在与不同的质子化试剂作用时，反应呈现完全相反的立体化学结果。

To compare the growth characteristics of non-hematopoietic adult stem cells derived from rat fetal blood and rat bone marrow in vitro, and to study the differentiation of these stem cells into neuron-like cells in vitro,the fetal blood of pregnant rats and bone marrow of adult rats were sterilely collected; mononuclear cells were isolated by using standard Ficoll-hypague techniques and then cultured in DMEM/LG containing 10% fetal bovine serum.
