A convenient one‐pot method for the synthesis of various substituted succinimides has been developed. By starting from commercially available amines (or ammonia) and alkynes, a range of interesting succinimides have been obtained selectively in the presence of either [Fe(CO)5] or [Fe3(CO)12] (see scheme; R′=H, alkyl, aryl; R′′, R′′′=alkyl, aryl).

The invention relates to a microfabricated valve (
10
), comprising a first channel (
11
), a second channel (
12
) and a connection channel (
13
). The connection channel (
13
) connects the first channel (
11
) and the second channel (
12
). The microfabricated valve further comprises a valve portion (
14
) arranged within the connection channel (
13
), wherein the valve portion (
14
) is adapted to selectively open and close the connection channel (
13
). Moreover the invention relates to a method comprising the steps: inserting the first channel (
11
) into the first layer (
21
), inserting the second channel (
12
) into the third layer (
23
), inserting the connection channel (
13
) with the valve portion (
14
) into the second layer (
22
), and then arranging the second layer (
22
) between the first layer (
21
) and the third layer (
23
). The invention relates furthermore to a test device, in particular for a biological application and in particular a method for performing a biological test cycle.

Succinimide derivatives are valuable compounds in synthesis of natural products and pharmaceuticals. A catalytic hydroaminocarbonylation reaction was developed for the synthesis of succinimides fromalkynes, CO and NH4HCO3. The novel transformation proceeds in the presence of Fe3(CO)12 without the need for expensive ligands or additives. Various substituted alkynes are selectively transformed into
