Jw. Herndon, The chemistry of the carbon-transition metal double and triple bond: annual survey covering the year 1997, COORD CH RE, 181, 1999, pp. 177-242
This survey is intended to be a comprehensive coverage of articles which re
port on the synthesis, reactivity, or properties of compounds which feature
a multiple bond between carbon and a transition metal. Reactions which emp
loy metal carbene complexes as transient intermediates generated through we
ll-established routes are not covered unless there is some effort to charac
terize the carbene complex intermediate. Only compounds which feature a mul
tiple bond between one carbon atom and one transition metal are discussed i
n this survey, thus bridging carbene and carbyne complexes are not covered
unless there is a multiple bond to one transition metal. The complexes of s
table carbenes with transition metals have not been included; since the rr-
donation component of these complexes is minimal, there is no formal carbon
-metal multiple bond (J.C. Green, R.G.; Scurr, P.R. Arnold, F.G.N., Cloke,
J. Chem. Sec. Chem. Commun. (1997) 1963; A.A. Danopoulos, D.M. Hankin, G. W
ilkinson, S.M. Cafferkey, T.K.N. Sweet, M.B., Hursthouse, Polyhedron 16(199
7) 3879). This survey has been divided into two sections, metal carbene (or
alkylidene) complexes and metal carbyne (or alkylidyne) complexes; the car
bene complex section represents the vast majority of this article. The meta
l carbene section has been organized according to metal, starting from the
left side of the Periodic Table. A special section focusing on alkene metat
hesis has been included prior to the discussion of carbene complexes of ind
ividual metals. The metal carbyne section has been organized according to r
eaction type. (C) 1999 Elsevier Science S.A. All rights reserved.
