Neutral formyl complexes which contain ligating CO often decompose by decarbonylation however, several exceptions exist. For instance, the osmium formyl hydride Os(H)(CO)2(PPh3)2(CHO) evolves H2(54). Although the data are preliminary, the cationic iridium formyl hydride 49 [Eq. (14)] may also decompose by H2 evolution (67). These reactions have some precedent in earlier studies by Norton (87), who obtained evidence for rapid alkane elimination from osmium acyl hydride intermediates Os(H)(CO)3(L)(COR) [L = PPh3, P(C2H5)3], Additional neutral formyls which do not give detectable metal hydride decomposition products have been noted (57, 65) however, in certain cases this can be attributed to the instability of the anticipated hydride under the reaction conditions (H2 loss or reaction with halogenated solvents).

Insertion of carbodiimides into Zr-C bonds is also observed. Zinc bis-amides insert only one equivalent of carbodiimide to give zinc guanidate complexes Ruthenium, osmium and iridium hydrides insert Ai,AI -(ji.p.tolylcarbodiitnide into their metal-hydrogen bonds to giveiV,Ai -p-tolylformamidinato derivatives .
