Abstract
This article deals with preparation of organocalcium compounds using calcium vapor (atoms). Calcium vapor (atoms) inserted into C-X bonds of organic halides, C-H bonds of benzene and cycloalkanes, Si-Cl and Ge-Cl bonds of chlorosilanes and chlorogermanes, and group 4 B element-group 4 B element bonds of group 4 B catenate compounds to give the corresponding organocalcium compounds, respectively. Several reactions of organocalcium compounds thus prepared with substrates were also examined.
