Sequential treatment of [M(![[triple bond, length as m-dash]](https://www.rsc.org/images/entities/char_e002.gif)
CBr)(CO)2(Tp*)] (M = Mo, W; Tp* = hydrotris(dimethylpyrazolyl)borate) with nBuLi, RPCl2 and LiCCSiMe3 affords [M{CPR(CCSiMe3)}(CO)2(Tp*)] (R = Ph, Cy) which are readily desilylated (TBAF) to provide the parent ethynyl derivatives [M{CPR(CCH)}(CO)2(Tp*)]. Alternatively, treating [W(CBr)(CO)2(Tp*)] with nBuLi, 1/2 PCl3 and LiCCR′ affords the alkynylbis(alkylidynyl)phosphines [R′CCP{CW(CO)2(Tp*)}2] (R′ = C6H5, C6H4Me-4, CMe3, SiMe3) and again the silyl derivative may be desilylated to the parent (R′ = H) which is readily converted to an arsino derivative (R′ = AsPh2). These novel architectures present new linkages for bridge-assisted polymetallic assembly.

炔基双（烷基亚炔基）膦：{L n MC} 2 PC CR †
用n BuLi，RPCl 2和LiC CSiMe 3连续处理[M（CBr）（CO）2（Tp *）]（M = Mo，W; Tp * =氢三（二甲基吡唑基）硼酸酯）提供[M { CPR（C CSiMe 3）}（CO）2（Tp *）]（R = Ph，Cy），它们很容易被甲硅烷基化（TBAF）以提供母体乙炔基衍生物[M { CPR（C CH）}（CO）2（Tp *） ]。或者，用n BuLi，1/2 PCl 3和LiC CR'处理[W（CBr）（CO）2（Tp *）]，得到炔基双（烷基亚炔基）膦[R'C CP {C W（CO）2（ Tp *）}2 ]（R'= C 6 H 5，C 6 H 4 Me-4，CMe 3，SiMe 3），甲硅烷基衍生物也可以被甲硅烷基化为母体（R'= H），后者很容易转化为砷化氢衍生物（R'＝ AsPh 2）。这些新颖的体系结构为桥梁辅助的多金属组件提供了新的连接方式。
