Bind reference to object

Hello everybody,

In a C#/WPF application, I'd like to know if it's possible to pass the reference to an object's property asCommandParameter.
Usually, I do something like this to send parameter to a command :

<Button Content="Send" Command="{x:static MyCommands.Send}" CommandParameter={Binding Path=Property1}"/>

Is it possible to pass the reference to Property1 to initialize it from aICommand ?

In C#, it's easy with the keywoard out but in WPF ... :(

Thanks in advance for your suggestions.
