The visible-light-driven preparation of (hetero)aryl stannanes was carried out under both photocatalyst- and metal-free conditions via irradiation of arylazo sulfones in the presence of hexaalkyldistannanes. The reaction shows a high efficiency and a wide substrates scope. The resulting crude organotin derivatives can be directly employed in a Stille protocol.

Sandmeyer-type stannylation: Stille coupling is one of the most powerful coupling reactions for C-C bond formation, whereas there are only limited methods to access aryl stannane compounds. A mild stannylation process based on a Sandmeyer-type transformation using aromatic amines as the starting materials is described. DCE: 1,2-dichloroethane. Copyright

Reagents containing carbon-tin-halogen inter-element linkages were effective for palladium-catalyzed carbostannylation. In situ generated allyltin trichlorides add to carbon-carbon double bonds of bicyclo[2.2.1]hept-2-ene (norbornene) and bicyclo[2.2.1]hepta-2,5-diene (norbornadiene), stereoselectively, under the catalysis of palladium(0) species in good yields. The regioselectivity of unsymmetrically substituted allylic reagents dramatically alters with the choice of the tin(II) salt. Aryltin trichlorides undergo palladium-catalyzed arylstannylation of norbornene, giving a mixture of products composed of that taking one norbornene and that taking two norbornenes. The product ratio is dependent on the choice of the solvent and electronic nature of the aromatic substituent.
Arylation of organotin halides with pentaarylantimony and pentaphenylbismuth

Pentaarylantimony and pentaphenylbismuth arylate oranotin halides R3SnX and R2SnX2 (R = Alk, Ar; X = Cl, Br) in toluene at room temperature to aryltin derivatives R3SnAr and R2SnArX (initial reagent molar ratio 1:1) or R2SnAr2 (2:1) in 78-95% yield.
Benzo-fused lactams promote release of growth hormone
-
, (2008/06/13)
There are disclosed certain novel compounds identified as benzo-fused lactams which promote the release of growth hormone in humans and animals. This property can be utilized to promote the growth of food animals to render the production of edible meat products more efficient, and in humans, to increase the stature of those afflicted with a lack of a normal secretion of natural growth hormone. Growth promoting compositions containing such benzo-fused lactams as the active ingredient therefore are also disclosed.

This property can be utilized to promote the growth of food animals to render the production of edible meat products more efficient, and in humans, to increase the stature of those afflicted with a lack of a normal secretion of natural growth hormone. The compounds are prepared by substitution of an amino-lactam with a substituted amide function. Growth promoting compositions containing such bezno-fused lactams as the active ingredient thereof are also disclosed. STR1 where L is STR2
