Unexpected reactions of (cyclooctatetraene) diiron hexacarbonyl with aryllithium reagents: Crystal structures of [(CO) 3Fe(1-4-η:5-7-η-C8H9)(CO) 2Fe(COC6H5)]

The reaction of (cyclooctatetraene)diiron hexacarbonyl (1) with aryllithium reagents ArLi (Ar = C6H5, o-, m-, p-CH3C6H4, p-CH3OC6H4) in ether at low temperature afforded acylmetalate intermediates. Subsequent alkylation with Et3OBF4 in aqueous solution at 0°C gave the (8,8-dihydro-1-4-η:5-7-η-cyclooctatrienyl)tricarbonylirondicarbonyl(arylfonnacyl)iron complexes [(CO)3Fe(1-4-η:5-7-η-C8H9)(CO)2Fe(COAr)] (2a-e) (2a, Ar = C6H5; 2b, Ar = o-CH3C6H4; 2c, Ar = m-CH3C6H4; 2d, Ar = p-CH3C6H4; 2e, Ar = p-CH3OC6H4) and (1-4-η:5-8-η-cyclooctatetraene)tricarbonylirondicarbonyl[ethoxy(aryl)carbene]iron complexes [(CO)3Fe(1-4-η:5-8-η-C8H8)(CO)2FeC(OC2H5)Ar] (3a-e) (3a, Ar = C6H5; 3b, Ar = o-CH3C6H4; 3c, Ar = m-CH3C6H4; 3d, Ar = p-CH3C6H4; 3e, Ar = p-CH3OC6H4). The structures of 2a and 3a have been established by X-ray diffraction studies, which indicate that the Fe(CO)3 unit and the (CO)2Fe(COC6H5) moiety in 2a and the (CO)2FeC(OC2H5)H6H5 moiety in 3a are on opposite sides of the cyclooctatetraene ring.

Systematic synthesis and crystal structures of tetraaryltellurium compounds Ar4TeIV

Hypervalent tetraaryltellurium(IV) compounds of the type Ar4TeIV(1: Ar = C6H5; 2: Ar = p-H3CC6H4; 3: Ar = p-t-BuC6H4; 4: Ar = p-F3CC6H4) were prepared via a convenient one-pot reaction between the isolated corresponding ArLi reagent and TeCl4. X-ray crystallographic analyses of 14 revealed distorted pseudo-trigonal-bipyramidal (TBP) structures for Ar4Te and the TBP character was analyzed by the dihedral angle method.

Synthesis of Benzosiloles by Intramolecular anti-Hydroarylation via ortho-C-H Activation of Aryloxyethynyl Silanes

Straightforward synthesis of benzosiloles was achieved by the invention of Pd/acid-catalyzed intramolecular anti-hydroarylation of aryloxyethynyl(aryl)silanes via ortho-C-H bond activation. The aryloxy group bound to the ethynyl carbon is the key factor for this transformation.
