Other Organometalloids

Arylboronic acid is the most versatile organometalloid due to its efficiency and ready commercial availability. Other organometalloids that can also participate in this copper-promoted cross-coupling reaction are aryltrialkylsiloxanes [51b, 54], aryltrime-thylstannanes [55], triarylbismuths [5,56], arylleads [57], diaryliodonium salts [58a], diethylzinc [58b] and dialkylaluminum chlorides [58c]. 

1 There are over 640 commercially available aryl boronic acids at last count in March 2004.

Chemical Abstracts (Dl) is undoubtedly the most convenient and comprehensive reference source, particularly since 1962 when a section devoted to organometallic and organometalloidal compounds was introduced. Information concerning books, review articles, and conferences is, however, extremely brief, and usually the subject matter of a particular entry must be judged solely from the title. Comparable publications in other languages include Chemisches Informationsdienst (D2) and Refera-tivnyi Zhumal, Khimya.
