A one-pot, two-step method for the synthesis of diynes and triynes is reported. The reaction of a dibromoolefinic precursor with BuLi effects a Fritsch-Buttenberg-Wiechell rearrangement and generates a lithium acetylide intermediate, which is then trapped

(Chemical Equation Presented) A divergent, one-pot synthesis of functionalized polyynes has been developed. Beginning with the appropriately substituted dibromoolefinic precursor, a carbenoid Fritsch-Buttenberg-Wiechell (FBW) rearrangement is used to gene
Ruthenium-catalysed double trans-hydrosilylation of 1,4-diarylbuta-1,3- diynes leading to 2,5-diarylsiloles

Dihydrosilanes undergo double trans-hydrosilylation with 1,4-diarylbuta-1,3-diynes in the presence of a cationic ruthenium catalyst to afford 2,5-diarylsiloles: in particular, 9-silafluorene is a good hydrosilylating agent to produce spiro-type siloles in good yield.
