Nucleophilic attack of a carbonyl oxygen atom of the complexes K[( η 5 ‐C 5 H 5 )M(CO) 3 ] (M=Mo, W) on each boron center gave the oxycarbyne complexes 1 . These novel products undergo a unique type of rearrangement with quantitative formation of the diborane(4)yl complexes 2 . Complex 2 (M=Mo) is the first structurally characterized boryl complex with a Mo–B bond (see structure).
