Direct Synthesis of Vinylene Carbonates from Aromatic Aldehydes**

Substituted vinylene carbonates were directly prepared from aromatic aldehydes following a one-pot Benzoin condensation/transcarbonation sequence under solvent-free conditions. The combination of a N-phenyl substituted triazolium salt NHC precursor and 4-dimethylaminopyridine (DMAP) was found essential to reach high yield and selectivity. The reaction scope was investigated with a range of aromatic aldehydes and the corresponding vinylene carbonates were obtained with 32–86 % isolated yields (14 examples).

A convenient and safe synthesis of 4,5-disubstituted-2-oxo-1,3-dioxolenes

Employing bis(trichloromethyl)carbonate (BTC), a safe and crystalline substitute of phosgene, 4,5-disubstituted-2-oxo-1,3-dioxolenes 3 have been synthesized by cyclocarbonylation of α-hydroxyketones 1 in 47-67% yield.

Neue Synthesen und Reaktionen ungesaettigter Heterotitanacyclen

Dicarbonyltitanocene reacts chemoselectively with difunctional carbonyl compounds such as 1,2-diketones and 1,4-diketo-2-enes, with α-ketothioketones, α-ketoimines and azodicarbonic esters and -amides to yield the corresponding, mostly new, heterotitanacycles that are capable of a lot of a useful follow-up reactions.These chelate complexes, containing three to four heteroatoms, allow the substitution of the entire titanocene fragment by carbon (formation of vinylenic carbonates and the thia-derivatives of these) or by further heteroatoms like boron or phosphorus(formation of boroles and phosphonic acid derivatives), thus retaining the cyclofunctionality.Alternatively, some of the new chelate complexes can be readily C-C-chain-lengthened via a deprotonating/alkylating sequence, leaving the metallacycle unaffected.
