✦ Synopsis

Only a few reports on hydroformylatio[l of alkynes with rhodium catalysts have appeared in the literature in recent years 1,2,3 . Normally, more vigorous reaction conditions are used then in the case of the corresponding olefins and only saturated aldehydes are formed in lower yields, To explain the lower reactivity of the allqnes in comparisorl with the olefins with respect to the rhodium catalyzed hydroformylation, the formation of rather stable complexes by interaction of the alkyne with the catalyst was taken into account2.

However, no information is available about the reaction mechanism up to date.
