# Vanadium (band)

Vanadium was an Italian heavy metal band from Milan, Italy. It was one of the first heavy rock bands to appear on the Peninsula and is considered among the most successful European exponents of the genre.

## History

Vanadium were founded in Milan in 1980 by Stefano Tessarin (guitar), Ruggero Zanolini (keyboards), Domenico Prantera (bass), Lio Mascheroni (drums) and Pino Scotto (vocals). Musically influenced by bands like Deep Purple, Thin Lizzy, Uriah Heep, Black Sabbath and Judas Priest, they had a difficult start due to scarce popularity of the metal genre in Italy, but managed to obtain a reasonable degree of success abroad. Following the break through of their first single We Want to Live with Rock 'n' Roll (Durium, 1981), they went on to record seven studio albums and the live On Streets of Danger (1985). Their third album, Game Over (1984), is possibly their most successful, with figure sales of about 54,000 copies.
Following the collapse of their label Durium in 1988, Vanadium recorded their last album Seventheaven with GreenLine before breaking up in 1990. They temporarily reformed in 1995 and released their only album entirely sang in Italian, Nel cuore del caos. Despite showing good form, the album wasn't commercially successful, and the band split up again and for good after a final tour.
After the demise of Vanadium, the band members pursued solo projects. Stefano Tessarin, with Ruggero Zanolini and Lio Mascheroni formed the band Rustless. Pino Scotto went on to start a solo career and recorded eight albums. Domenico Prantera retired from playing music professionally and started managing emerging bands.
On 11 May 2014, the Italian publisher Crac Edizioni published the official Vanadium biography authored by music journalist Luca Fassina.

The relatively complex nature of the formal names for DBU and DBN (hence the common use of acronyms) reflects the fact that these compounds are bicyclic and contain several functional groups.

## Synthesis

DBN could be synthesized in the following manner, similarly to DBU:
The synthetic procedure starts with a Michael addition of 2-pyrrolidone to acrylonitrile, followed by hydrogenation, and finally dehydration.

## Uses
### As a base in organic synthesis

Similar to many other organic bases, DBN could be employed for dehydrohalogenation reactions, base-catalyzed rearrangement reactions, as well as Aldol condensation. Several examples are shown below:
* Elimination:
* Epimerization of penicillin derivatives, catalyzed by DBN:
* Aldol condensation:

### DBN salt as an ionic liquid

The acetate salt of DBN is a room-temperature ionic liquid used for processing cellulose fibers by acting as a replacement for the unstable N-Methylmorpholine N-oxide used for making lyocell.
