Group-IIIB Halides

Group-IIIB halides ( 6.5.2), through interaction with neutral metal bases, lead to acid-base adducts in which the group-IIIB elements possess higher coordination numbers than before ( 6.5.2.1) ... [Pg.54]

Anionic metal bases react with group-IIIB halides by eliminating halide anions, forming neutral, c-bonded IIIB-metal compounds ( 6.5.2.2) ... [Pg.54]

Formation from Group-IIIB Halides 6.5.2.I. by Reaction with Neutral Metal Bases... [Pg.55]

Neutral transition-metal complexes that are not fully coordinatively saturated possess nucleophile metal centers capable of coordinating to electrophiles. On the other hand, group-IIIB halides serve as typical electron-pair acceptors and are, therefore, able to interact coordinatively with basic metal complexes. [Pg.55]

Group-IIIB halides react with Co2(CO)g to form Ga— and In — Co bonds ... [Pg.55]

This reaction is a principal method of forming IIIB-transition-metal cr bonds. The formation of thermodynamically favored alkali-metal halides or related salts and acids HX enhances the easy formation of those bonds. A second possible interaction between anionic metal bases and group-IIIB halides is a simple acid-base relationship without elimination of halide anions. However examples of this are rare, and they have been described often for group-IIIB compounds without halogen ligands ( 6.5.3.2). [Pg.57]

Formation from Group-IIIB Halides G.5.2.3. by Oxidative-Addition Reactions... [Pg.64]

Reactions of dinuclear transition metal carbonyls with Ga, In, or T1 in the +1 state proceed by oxidative addition, which leads to insertion of the group IIIB element into the metal-metal bond. From the reaction of InBr with Co2(CO)8 in THE, the product is BrIn[Co(CO)4]2-THF, while the halides Ga2X4 (X = Cl or Br) yield XjGaCoICO) THE, in which both Ga centers attain the +3 stateh The same products can be isolated from reactions of the group IIIB halides, MX3, with NaCo(CO)4 or Co2(CO)g in Thfi-3. [Pg.301]
