“… In both cases, excess PPh 3 was needed to limit the formation of dinuclear side products of the form [(PPh 3 ) 3 Co(CO)] x (in which the authors propose that x is most likely 2, but these byproducts were not fully characterized). Subsequently, Gallo et al demonstrated that the related compounds (L) 3 Co(N 2 )(H) [L = PPhEt 2 ( 1b ) or PPh 2 Et ( 1c )] and (L) 3 Co(H) 3 [L = PPhEt 2 ( 3b ) or PPh 2 Et ( 3c )] undergo analogous CO 2 insertion reactions . They also showed that there is no reaction between CO 2 and the complexes (L) 4 Co(H) [L = P(OMe) 3 , P(OEt) 3 , P(OPh) 3 , P(O n Bu) 3 , P(OPh) 2 Ph, or P(OEt) 2 Ph], even at elevated temperature .…”

On the basis of these results, the authors suggested that the first step in CO 2 insertion with 1a – 1c is dissociation of N 2 and coordination of CO 2 . …”

Carbon dioxide (CO 2 ) is an appealing feedstock for the sustainable preparation of a variety of carbon-based commodity chemicals because of its high abundance, low cost, and nontoxicity. The high kinetic and thermodynamic stability of CO 2 , however, means that there are currently only a limited number of practical catalytic systems for the conversion of CO 2 into more valuable chemicals, and continued research in this area is required. One promising approach for the eventual transformation of CO 2 is to initially insert the molecule into transition-metal−element σ bonds such as M−H, M−OR, M−NR 2 , and M−CR 3 bonds to form products of the type M−OC(O)E (E = H, OR, NR 2 , or CR 3 ). CO 2 insertion has been demonstrated in numerous stoichiometric reactions involving transition-metal complexes, but in cases where insertion results in the formation of strong M−O bonds, the products are often too stable to undergo further transformations. Group 9 and 10 transition-metal complexes (M = Ni, Pd, Pt, Co, Rh, or Ir) form relatively weak M−O bonds, and as a consequence, a number of group 9 and 10 transition-metal catalysts in which CO 2 insertion is proposed as an elementary step in catalysis have been developed. In this Award Article, we summarize group 9 and 10 transition-metal complexes in which CO 2 insertion into a metal−element σ bond to form a M−OC(O)E-type product has been observed. Mechanistic similarities and differences are highlighted by comparing CO 2 insertion reactions in different types of group 9 and 10 metal−element σ bonds, and a general trend for predicting the ratedetermining step of the insertion process is described based on the nucleophilicity of the element in the σ bond. Although we focus on stoichiometric reactivity, the relevance of CO 2 insertion to catalytic reactions is also emphasized throughout the paper.

Das Kohlendioxidmolekiil hat bislang nur eine geringe Bedeutung als Synthesebaustein in der Organischen Chemie. Uber seine Koordination an Ubergangsmetalle ergeben sich jedoch vollkommen neue Reaktionsmoglichkeiten: C 0 2 wird in vielfaltiger Weise an Metallkomplexen fixiert, kann stochiometrische Kupplungs-und Insertionsreaktionen eingehen sowie katalytisch mit anderen Substraten verkniipft werden. Insbesondere die homogenkatalytische C-C-Verknupfung von Kohlendioxid mit ungeslttigten Kohlenwasserstoffen eroffnet neue Wege zu technisch interessanten organischen Verbindungen.
