Matching security group names based on $variable.name - powershell

Question

Ok so I'm trying to automate the creation of security groups under a specific OU. The keystone is group membership, so basically If member of group A -> create group B.
So I'm filling a variable with the name attribute of an "All Managers" group. Then I want to loop through those $names and check for the existence of another group using {Name -like 'Reports to $name'}
The looping part is throwing me off, here's what I've got:
import-module activedirectory
$ou = "ou=Stuff, ou=Resources, ou=Groups, ou=Org, dc=domain, dc=net"
$creds = "domain.net\user"
$server = "<domain controller>"
$managers = get-adGroupMember -server $server -Credential $creds -identity "All Managers" | select name
$name = $managers.name
$ReportsTo = Get-adgroup -server $server -credential $creds -searchbase $ou -filter "Name -like 'Reports to *'" | where {$_.name -replace 'Reports to ' -in $name} | select name
$Reports = $reportsto.name
$reports
ForEach ($manager in $managers){
If ($ReportsTo -NotContains $name)
#{$name}
{New-ADGroup -name "Reports to "$name -groupscope Global -path $ou}
}
it's ugly I know, but like i said I'm not sure how to process the loop, they are still new to me.

You may do the following:
$ou = 'ou=Stuff,ou=Resources,ou=Groups,ou=Org,dc=domain,dc=net'
$creds = "domain.net\user"
$server = "<domain controller>"
# Get Manager names only
$managers = Get-ADGroupMember -Server $server -Credential $creds -Identity 'All Managers' |
Select-Object -ExpandProperty Name
# Get Group names that are in the format Reports to Manager Name
$ReportsTo = Get-ADGroup -Server $server -Credential $creds -SearchBase $ou -Filter "Name -like 'Reports to *'" |
where {$_.Name -replace 'Reports to ' -in $managers} |
Select-Object -ExpandProperty Name
# Find manager names that don't have a Reports to group
Compare-Object $managers ($ReportsTo -replace 'Reports to ') -PassThru | Foreach-Object {
# Pipe found manager names into New-ADGroup command's -Name parameter
New-ADGroup -Name "Reports to $_" -GroupScope Global -Path $ou -Server $server -Credential $creds
}
Compare-Object by default only lists differences.
