Notes:
The reaction of pivaloylethoxyacetylene with silicon halides, which has been found to occur as a 1,4-addition, leads to allenic ethers, which readily eliminate ethyl halides and are converted to previously unknown types of ketenes - stable element-substituted acylketenes. Germanium-substituted acylketenes are also formed; however, clear evidence of 1,4-addition of germanium halides was not obtained. In the reaction between Ph2PCl and pivaloylethoxyacetylene, phosphorus (III) substituted acylketenes initially formed underwent rapid [3 + 3] cyclodimerization.
