The ?eld of metal boron chemistry has been an especially active one
since the 1960s. Much of the early work centered on the synthesis
and structural characterization of polyhedral metallaborane and
metallacarborane clusters, which will not be discussed in the
current Volume. However, early work on metal boryl complexes by
Noth et al. also appeared during this period, - thoughthe?rstsimple

ouslybyBaker,Marder,etal. [1]andbyMerolaetal.
[2]),andthisnewinterest in the area arose speci?cally as a result
of the report by Noth et al. [3] on the rhodium-catalyzed
hydroborationof alkenes using catecholborane. Although there had
been previous reports of metal-catalyzed hydroboration employing
polyhedralboranesorcarboranesastheB-Hsource[4], theseminal paper by
Noth et al. in 1985 [3] marked the beginning of interest by the
organic ch- istry community in the application of this reaction in
organic synthesis [5].

arenes, heteroarenes, and even alkanes[9,10].

metal borylcomplexes are key intermediates. Likewise, the
importance of metal borane?-complexes as intermediates in many
catalytic reactions has only recently been recognized [12], and
thisarea is now a rapidly expanding one.
