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.
