The problem is that your first expression isn't syntactically valid, so
I presume what you really mean is something like transforming
{{a, b, c}, {d, e, f}, {g, h, i}}
into say
fun[x,y,{a, b, c}, {d, e, f}, {g, h, i},z]
In other words that you want to embed it in something else:
In[1]:= tmp = {{a, b, c}, {d, e, f}, {g, h, i}}
Out[1]= {{a, b, c}, {d, e, f}, {g, h, i}}
In[2]:= fun[x, y, Sequence @@ tmp, z]
Out[2]= fun[x, y, {a, b, c}, {d, e, f}, {g, h, i}, z]
