I have an iMac 27-Inch "Core i5" 2.7 (Mid-2011) and I want to connect a Thunderbolt 3 (USB-C) hub via the Thunderbolt 1/2 port.

In all my searching I could only find a Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter. The only issue is that I need the opposite, as most of the hubs I have found seem to have a Thunderbolt 3 connector.

So I am looking for a Thunderbolt 2 to Thunderbolt 3 (USB-C) adapter that will let me plug the Thunderbolt 2 port into my iMac and connect the Thunderbolt 3 port to a hub like this.

The Apple part is bi-directional, but since the hub you want to work is USB and not Thunderbolt, I would use a much less expensive USB A to USB C adapter to test. You will likely not get the power or signaling to make USB-C 3.0 to work without a proper thunderbolt dock. The adapter you have will let a TB 3 dock work as will the less expensive (perhaps used) Thunderbolt 2 docks like Belkin, Elgato or OWC.

The best way to get USB 3.0 from a TB 2 mac is this part, but it’s not got as many output options as the inexpensive USB-C devices or the proper docks above, but it splits the difference between your hub and the full dock price.

The Apple TB2 to TB3 adapter is bidirectional but it will only work on docks that are Thunderbolt. If there is an attached USB-C cable then it will not work with that Apple adapter. If the dock has any other than a USB-C/TB3 port on it then it will not work with that adapter. USB 3.x docks will not work.

You will need that TB2 to TB3 adapter, a TB2 cable, and a Thunderbolt dock like this: https://eshop.macsales.com/item/OWC/TB3DK14PSL/

As bmike points out you may be able to get by with a cheaper mini-dock that doesn't need the Apple TB2 to TB3 adapter, if your port needs are simple:
