    Description / Table of Contents: Cyclic Analogues of Divinylstannanes, Divinylboranes, and pentahapto-Divinylborane ComplexesThe dialkynes X(C ≡ CH)2 with X=(CH3)2C, (CH3)2Si, and (CH2)2 afford the stannacyclodienes X(CH≡CH)2Sn(CH3)2 on hydrostannation with (CH3)2SnH2. These are transformed into the 1-phenylboracyclodienes X(CH=CH)2BC6H5 by treatment with C6H5BCl2. Complexation reactions yield the transition-metal complexes [X(CH=CH)2BC6H5]Fe(CO)3 and (C5H5)Co-[(CH3)2C(CH=CH)2BC6H5] wherein the ligands act as pentahapto-ligands. The structure of tricarbonyl(1,1-dimethyl-4-phenyl-1-sila-4-bora-2,5-cyclohexadiene)iron (6b) is determined by X-ray methods.
    Notes: Die Dialkine X(C ≡ CH)2 mit X — (CH3)2C, (CH3)2Si und (CH2)2 liefern bei der Hydrostannierung mit (CH3)2SnH2 die Stannacyclodiene X(CH=CH)2Sn(CH3)2. Diese werden durch Umsetzung mit C6H5BCl2 in die 1-Phenylboracyclodiene X(CH=CH)2BC6H5 übergeführt. Komplexierungsreaktionen ergeben die Übergangsmetall-Komplexe [X(CH=CH)2BC6H5]Fe(CO)3 und (C5H5)Co[(CH3)2C(CH=CH)2BC6H5], in denen die Boracyclodien-Liganden als pentahapto-Liganden fungieren. Die Struktur von Tricarbonyl(1, 1-dimethyl-4-phenyl-1-sila-4-bora-2,5-cyclo-hexadien)eisen (6b) wird röntgenographisch bestimmt.
